Introduction
Applications
The MPR15 / MPR25 rectifiers are designed to operate continuously in
a battery-equipped or batteryless –48 V power system, either embedded
as part of a small system, or as part of a power plant in a system
application.
Several models are available for operation in a controlled environment.
An extended temperature version is capable of withstanding
temperatures ranging from -40°C to +65°C while standard models
operate from 0° to +65°C ambient. The MPR15EX model operates in
an ambient temperature range of −40°C to +50° C, and the standard
MPR15E operates in a range of 0°C to +50°C.
The MPR25E and MPR25EX are suitable for various embedded and
system applications. These models offer features that facilitate
installation, operation and maintenance.
The MPR15EX is intended for low power applications, when only 110 /
120 V AC power is available.
The rectifier will operate with existing Astec rectifiers and other compatible
manufacturers' products. It is compatible with Astec conventional and
microprocessor-based controllers designed to interface with the basic
standard signals.

Operation
Rectifier operation
The main AC line voltage is rectified and filtered to an unregulated high DC
voltage. The input circuit provides EMI filtering, inrush current limiting, low
and high AC inhibition, lightning and surge voltage protection, and input
fault protection through an AC breaker.
The high frequency isolating power section consists of a full bridge
converter using power MOSFETs and a high frequency power
transformer.
The high frequency AC voltage generated at the secondary of the power
transformer is rectified and filtered. The output section provides EMI
filtering, a shunt for output DC current sense, and output protection in
the form of a DC breaker. A current mode pulse width regulator varies
the pulse width of the signal driving the power MOSFETs. This allows
regulation to the output DC voltage.
The monitoring circuitry includes soft start, rectifier fail alarm (RFA),
rectifier RFA/ON LED, local and remote equalize, temporary release,
thermal shutdown, AC valid, local and remote high voltage shut down
(HVSD), local and remote HVSD reset, logic valid, fan failure detection,
and a fan failure LED.
A three-digit output current meter reads the output shunt and displays
the value using an integrated logic circuit.
An auxiliary power supply provides the various voltages required by the
internal circuitry and cooling fan.

Operation 23
Rectifier failure alarm (RFA)
The rectifier incorporates facilities for monitoring its operational state and
extends a global alarm upon detection of an internal failure or a no load
condition (see Note below). When the rectifier operates in parallel with
other rectifiers and its output voltage is adjusted lower, the RFA LED will
change to RED and an RFA alarm will be sent.
Note:
Give an alarm at no load condition only for the following
releases or under.

Rel. 10
NT5C06CB, CB-1, CB-3, CD
Rel. 12
NT5CO6CE-61(-46)
Rel. 12
Fan failure alarm
A fan failure will activate the fan alarm and inhibit the operation of the
rectifier. An RFA will also be issued upon inhibition of the rectifier.
Internal high voltage shut down (HVSD)
The rectifier includes a high voltage monitor. Whenever the rectifier output
voltage exceeds a value adjustable from -52 to -59.5 V it shuts down
immediately, locks out, and transmits an RFA. This function is not
dependent on the output load condition.
Local ON/OFF control (DC and optional AC breakers)
Circuit breakers are used to turn the rectifier ON/OFF locally and
disengage it from the DC circuit. The local OFF control overrides the
remote control signals.
Inrush current limiting fuse (F1)
A 3/4 A, 250 V fuse is connected in line with the soft start circuitry to
protect the input circuitry against high inrush currents in case of an
internal failure. On the MPR15E modes NT5C06CB/CD/CE, failure
of this fuse during operation will disable the unit. See the
“Recommended Replacement Parts” section to order a replacement
fuse.
25A Switch Mode RectifierNT5C06B / C Installation and User Manual
24 Operation
Test points (V+, V-)
Test points allow the user to measure the voltage at the point of regulation,
whether the DC breaker is ON or OFF. A 10 K resistor is placed in series
with the –48 V lead to prevent short circuits at the jack terminals.
Current meter
A three-digit output current meter, available on the enhanced model, reads
the output shunt and displays the value using an integrated logic circuit.
Fan filter option
A fan filter option is available for dusty environments to prevent the dust
particles from entering and deteriorating the cooling efficiency of the
rectifier. (See the “Recommended Replacement Parts” section to order an air
filter kit.)
The maximum operating ambient temperature should be limited to 50°C
(122°F) for environments requiring the rectifier air filter.

UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
Operation 25
Signal connector
This connector provides control and monitoring signal access to the rectifier.
Refer to the “Signal Connections” section for connection details.
Power interface edge connector
The rectifier AC, DC and chassis ground interface is made through the rear
edge connector. Refer to the “Rectifier and Controller Interface
Connections” section for connection and installation details.
Features
The rectifier provides the following operating, monitoring, measurement and
control features:
Operating features
Remote voltage sensing
Provision is made to extend the sensing leads to the battery or to the
charge/discharge bus (operation without batteries) of the plant. The opening
of either sensing leads will not result in a voltage increase at the rectifier
output terminals.
Current limiting
The rectifier will automatically limit the output current to 17.5 to 20 A
(MPR15) and 25.5 to 30 A (MPR25). Extended periods of operation in the
current limiting mode, and repeated transitions between constant-voltage
operation and constant-current operation have no detrimental effect on the
performance or service life of the rectifier.
The rectifier is capable of starting when connected across a completely
discharged battery without requiring human intervention or operating
protection devices.
Transitions from constant-voltage operation to constant-current operation
and from constant-current to constant-voltage operation will occur
automatically, as determined by the output current. The current limit circuit
will continue working in both the float and equalize modes.
Soft start and walk-in
The output current rises from 10% to 90% in 2 seconds (typically).
25A Switch Mode RectifierNT5C06B / C Installation and User Manual
26 Operation
AC inrush current
The AC current during the turn on sequence of the rectifier, under all input
and output conditions specified in this document, will not exceed its full load
steady-state value.
Sequential start
The rectifier Temporary Release (TR) leads are available for use with an
external sequential start circuit.
Parallel operation
The rectifier is capable of operating in parallel with other rectifiers having
similar output slope characteristics.
Discharge of output capacitors
The output capacitors will automatically discharge when the rectifier is
disconnected and the AC power has been removed.
Load sharing
Rectifiers connected in parallel and sensing at the same point will share the
load with other rectifiers having similar negative output slope characteristics
(300 mV drop from zero to full load).
The rectifier will share the load proportionally to its output rating to a
precision within +10%.
Monitoring features
Input AC voltage monitor
The rectifier monitors the input voltage and inhibits its operation when the
voltage exceeds the specified limits. Refer to the “Summary of
Specifications” section, sub section Electric. An RFA is initiated.
The rectifier recovers its normal operation automatically when the specified
input voltage is re-established.
Thermal shutdown
The rectifier protects itself against thermal overstress by inhibiting its
operation for the duration of the high temperature condition. The RFA
alarm is triggered. The rectifier will restart after the temperature has returned
to a safe level.
UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
Operation 27
Output current monitor
The rectifier monitors the output current. The unit will initiate an RFA alarm
when no output current (see Note below) is detected during parallel
operation.
Note:
Give an alarm at no load condition, only for the following
releases or under.
NT5C06BB, BB-1, BB-3, BC

Rel.12
Measurement features
Remote rectifier current measurement
The rectifier is equipped with a 50 mV / 25 A shunt connected on the
positive lead, near the output terminals. The shunt signal is available on the
signal connector (see Figure 3).
Test points (V+, V-)
Voltage jacks are provided for measuring the voltage at the point of
regulation.
Control features
Remote ON/OFF control
When a ground signal is applied to the 'Temporary Release' (TR) input, the
rectifier inhibits its operation and activates the rectifier's RFA. Upon removal
of the remote ground signal the rectifier returns to normal operation.
Remote high voltage shutdown
In addition to the local high voltage shutdown feature, the power plant
controller can shut down any rectifier by sending a high voltage shutdown
signal, ground (BAT RTN) pulse. The rectifier will shut down if it is
supplying more than 10% of its full load rating.
25A Switch Mode RectifierNT5C06B / C Installation and User Manual
28 Operation
Local/remote high voltage shutdown reset
The rectifier may be reset from an HVSD condition locally, by resetting the
AC circuit breaker (if so equipped), the associated AC breaker on the
distribution panel, or remotely by applying a ground signal at the HVSDR
input of the rectifier provided:
•
the 'TR' lead is not activated
•
the 'AC' (optional) and 'DC' breakers are closed
Remote equalize control
The rectifier is equipped with remote equalize control. This function is
operated by applying a remote ground signal (BAT POS) and returns to
normal (Float) operation upon removal of the signal.
Signal connections
The interface connector located at the rear of the rectifier provides control,
alarm and monitoring signals. The control inputs are activated by a ground
(BAT RTN) signal. The alarm contacts are extended by relays and are
isolated from each other, and from the rectifier chassis. All contacts are rated
60 V DC and 0.5 A.

Cabling the power shelf
The AC and DC cabling size and routing inside the shelf are determined by
the following shelf configurations. Refer to Figures 13 to 20 for routing.
Note:
The grounding of the shelf is provided by the AC
armored cable ground wire attached to a two-hole ground
lug located on the inside wall of the shelf chassis. The
shelf is also grounded to the rack or cabinet frame by one
of the shelf mounting screws which is installed with an
external tooth washer. This grounding method is
sufficient but if desired, an extra ground cable (color
green insulation 105°C), of size 8 AWG for common AC,
or 12 AWG for individual AC applications, can be
installed in addition to the existing cable and be
connected to an external system ground. Using a 0.25inch ring lug terminal, the new ground wire can be
installed on one of the existing ground lug screws located
inside the shelf. Route the wire along the inside top back
of the shelf and make it exit out of the right DC cabling
side opening. Ensure the wire does not interfere with the
rectifier connections. See Figure 13 for the extra ground
connection mounting location.

The connections available from the rectifier interface connector located
at the rear of the unit are described in the “Rectifier and controller
interface connections” section of this manual.
Refer to the reference section for all the interface signal wiring
information for each shelf model number.
Following is a brief description of special interface or alarms signals for
specific applications.
NT5C10BA-1/2, NT5C10BF-1 and NT5C10BP hot standby power
shelf
The NT5C10BA-1/2, NT5C10BF-1 and NT5C10BP wiring is such that
when the power shelf is equipped with two or more rectifiers, one rectifier is
inhibited (Standby) and will be activated when one rectifier (Main or Regular)
fails.
These power shelves are equipped with a relay that provides an alarm signal
no standby rectifier (NSR) when the standby rectifier is missing from its
position. Also two RFA signals are available for transmitting the alarm signal
to the monitoring unit.
Note :
The earlier vintage "Main" rectifier has been referred to
as the "Regular" rectifier. See Appendix A for additional
information on the NT5C10BF and NT5C10BP shelves.

Installation and start-up procedures 55
NT5C10BA-3/4 special operating signal - AC fail NC
Originating from a time delay relay, this signal indicates the state of the line
input voltage of the left rectifier in the shelf. This relay, which is normally
closed, will open after a delay of 8 to 10 seconds following the removal of
the AC line input. The indicator should be set to #6.
Note :
The standby HVSD rectifier should be adjusted 0.5 V
higher than the main rectifier, and its float voltage 0.1 V
lower than the main rectifier.
NT5C10BJ & NT5C10BK
The NT5C10BJ and NT5C10BK power shelves (23-inch mounting) are
designed for embedded applications. The NT5C10BJ is brown and the
NT5C10BK is dolphin grey. Both power shelves can be equipped with two
MPR15 and MPR25 rectifiers and a low voltage disconnect unit
(NT6C13FC), or with two rectifiers, one RPM1000C and one low voltage
disconnect unit without a control circuit pack (NT6C13FJ).
When the NT6C13FJ unit is used, the RPM1000C performs the control
and monitoring functions. The NT6C13FJ is equipped with an interface
circuit pack that receives the LVD signal from the RPM1000C (battery
return) to open the LVD contactor. It is equipped with a bypass switch.
The function of the BYPASS switch is to prevent accidental release of
the LVD contactor during maintenance, or when the RPM1000C is
being replaced.
The power shelves are offered in the two configurations described above.
When the RPM1000C is not provided, the power shelf is equipped with the
NT5C10PC interface circuit pack. The function of this circuit pack is to
connect the rectifier control cables (J1 and J2) and the alarm cable (J3). The
connector pin assignments are listed in Table 10.

NT5C10BM
The NT5C10BM power shelf (23 inch mounting) is wired to accept the
NT5C10KB local equalize feature. It can house up to three MPR15 or
MPR25 rectifiers and is wired for common AC input, 120 / 208 / 240 V AC.
When the equalize switch is set to the EQL position, a battery return signal is
sent to the remote equalize input port of each rectifier in the power shelf.
The rectifier output voltage will increase by the amount set with the EQL
adjustment potentiometer of the rectifier. Each rectifier must be individually
adjusted to the same equalize voltage level. The yellow LED indicates that
the rectifiers are in equalize mode.
NT5C10KA & KB
This option is offered with the embedded power shelves to provide local
equalize. The power shelf must be pre-wired in order to install this feature.
The NT5C10KA is brown and the NT5C10KB is oxford grey.
Note :
It is recommended that the rectifiers be inserted in the
shelf from right to left, starting with position 1. When a
Low Voltage Disconnect unit is available, the LVD must
be mounted to the right of position 1.

Installation and start-up procedures 57
NT5C10KC
This option is offered to provide an AC Fail Alarm upon loss of the input
line power. Selectable for 120 or 208 / 280 V AC operation, the circuit
provides a dry C form contact relay, TB1-1 (NC) and TB1-2 (C), to send an
alarm. See User Manual (UM) supplement P0803489 for more information.
NT5C10CO
This power shelf houses two rectifiers. One rectifier operates in the standard
mode (no delay) and the other is inhibited for a fixed amount of time after an
AC power failure. The delayed start is required to allow time for the batteries
to recharge, and the required total AC input current for the two rectifiers to
be reduced to less than 20 amperes.
The rectifier that is delayed will be activated immediately if the main rectifier
fails, is pulled out or missing, or produces an RFA. The delayed start rectifier
will not transmit an RFA signal to the controller during the time that it is
inhibited, but it will transmit an RFA signal to the Controller after the
delayed start period, if the DC or AC circuit breaker is open.
When the rectifier is on the delayed start mode, the RFA LED on the
rectifier will be lit (red). The “DELAYED START” yellow LED of the timer
will be ON indicating that the rectifier with the red RFA LED is on delayed
start mode.
See Appendix B for additional information on the NT5C10CO shelf.

Low voltage disconnect 71
Operation
The battery voltage is monitored by the low voltage disconnect and low
voltage alarm circuit (LVA). When the voltage drops to approximately -47 V
DC, the LVA LED lights up and the alarm is extended to the terminal block.
When the battery voltage drops to the low voltage disconnect level, the
contactor opens, disconnecting the load from the battery. This turns the
LVD LED ON and activates the low voltage disconnect alarm. When the
battery voltage rises by approximately 8 V (adjustable) above the release
level, the load is reconnected to the batteries and the alarm is cleared.
The LVD potentiometer sets the level at which the load disconnects and the
LVDR potentiometer sets the level at which the load reconnects. Test jacks
(TP1 and TP2) provide the plant discharge voltage when the 'TEST' switch is
set to NORMAL.
Test feature
The internal test feature facilitates the verification of the low voltage
disconnect, reconnect, and low voltage alarm circuitry, without disconnecting
the load.
When the panel switch is set to 'Test/Bypass' a ground signal is applied to
lock the LVD contactor and the 'TEST' potentiometer is connected in series
with the control circuit. Varying this potentiometer will affect the voltage
senses by the LVD and LVA detectors. This test voltage can be verified at
test jacks TP1 and TP2.
Signal connections
The signal connections are shown in Figure 26 of this manual (see the
“Operation” chapter of this manual for the installation of the low voltage
disconnect unit).

Procedure 20 - Float/equalize and remote equalize
Step
Action
1
Disconnect the sense leads from the rectifier, by either disconnecting a
quick disconnect tab TB1 on the shelf or removing the appropriate
system fuse. (See the “Introduction” chapter for system applications.)
Open the output DC breaker. The unit is ready for local adjustment.
The unit should provide voltage to the front panel test point terminals. If
it does not, cycle the AC breaker to reset the unit.
Momentarily hold the FLT/EQL switch to EQL for local equalize.
Using a voltmeter, verify and adjust the EQL potentiometer to obtain an
output voltage reading of 0.5 volts (see Note below) above the system
equalize requirement.
Release the FLT/EQL switch. Verify that the output voltage drops to the
float value plus 0.5V (see Note below).
Verify the HVSD level. It is recommended that it be set approximately 3 V
above the shutdown limit of the power system. Refer to the “Installation
and start-up procedure” chapter, subsection “Start-up procedure”, for the
verification procedure.
Reconnect the sense leads locally to the rectifier. Close the output DC
breaker. Cycle the AC breaker to reset the unit. The RFA/ON LED should

74 Maintenance
Filter
If the unit operates in a dusty environment the optional fan filter is
recommended. It must be inspected and replaced, or thoroughly cleaned, at
least every 12 months.
CAUTION
Do not install a wet filter in the unit.
To remove the filter, simply unscrew it. Re-install it by reversing the
operation.
Fan cooling
Visually inspect the intake of the airflow for any obstruction by foreign
objects or excessive dust and dirt build-up. Open both the DC and AC
breakers (toggle them to OFF) and remove the unit from the power shelf.
Inspect the air outlet for obstruction by foreign objects. Visually inspect the
air outlet of the enclosure or cabinet. If a problem is detected in the rectifier,
contact your local Astec service facility. The unit must not be opened for onsite servicing.
DANGER
Do not attempt to access the inside of the unit with a
tool or finger. Severe electrical shock could result.
Storage
The rectifier contains aluminum electrolytic capacitors. For this reason, the
rectifier must be in operation. If not in operation, once a year, the equipment
must be energized for at least two hours to maintain the electrolytic
capacitors in working condition.
Power shelf
The rectifier shelf requires no maintenance.
UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
Maintenance 75
Low voltage disconnect
The LVD voltage adjustment levels should be verified periodically
(preferably at intervals no greater than one year). Refer to the “Fault
diagnosis” section found at the end of this chapter for the verification
procedure. When the verification has been completed, set the Test/Bypass
switch to the Normal position.
The DC connections on the main contactor should be tightened with a torque
wrench set at 70 in.-lb. periodically (at one-year intervals) to avoid the build
up of hot spots and voltage drops.
Troubleshooting
Rectifier fail alarm
Verify that the input AC voltage is within the specified limits.
Cycle the AC breaker off/on to reset the unit from a possible HVSD
shutdown.
Make sure the HVSD potentiometer is adjusted properly. Refer to the “Startup procedure” section of the “Installation and start-up procedure” chapter of
this manual for the adjustment procedure.
If the unit is used in parallel with other units the rectifier may indicate an
RFA alarm when the unit produces no current (see Note below). This could
mean that the float voltage is too low. Increase the float voltage by turning
the FLT potentiometer clockwise until the ON/RFA led turns green.

Load sharing
Verify that the sense leads of all the rectifiers are connected to a common
point (across the battery or output power terminals of the power shelf, or at
the discharge busbar).
Readjust the rectifier’s float voltage until all the rectifiers share the load. It is
recommended that the current from each rectifier be 3 amperes minimum
for best results.
It is also recommended to leave the units functioning for at least 30 minutes
to reach full stability, prior to final system adjustment.
Fan failure
Fan failure is indicated by the absence of fan rotation. The rectifier will be
inhibited and an RFA and Fan alarm will be activated. The Fan Fail LED will
turn RED.
Fan replacement procedure
DANGER
Before replacing the fan, turn the rectifier off. Remove the
rectifier from the shelf. Wait five minutes to allow all

Appendix A: NT5C10BF-1 and NT5C10BP
Purpose
This appendix provides additional information about the NT5C10BF-1
(brown) and NT5C10BP (grey).
Application
The NT5C10BF-1 and NT5C10BP power shelves are used in the FTIP and
FTOP application. This power shelf provides housing for two MPR15E
rectifiers plus one 50 A LVD, FTIP application, or three MPR25EX
rectifiers, FTOP application. In both applications the rectifier in the center
will be wired for standby operation (standby means that this rectifier will be
inhibited under normal operation and will become active when another
rectifier in the same power shelf issues an RFA).
FTIP application
The MPR15E (NT5C06CB/CD) rectifier is used in this application. Two
rectifiers maximum can be used in each system, plus one 50 A LVD. The
main rectifier is active and carries the load, and the standby is inhibited. It
will be activated upon removal or failure of the main rectifier (hot standby
model).
During transfer from a failed “MAIN” unit to a “STANDBY” unit the load
current will be supplied by the backup batteries. The standby unit will
provide the required current within 10 seconds.

Appendix B: NT5C10CO shelf
General
This appendix contains supplementary information for the NT5C10CO
"DELAYED START" power shelf.
NT5C10CO power shelf
Description
The power shelf houses two rectifiers. One rectifier operates in the standard
mode (no delay) and the other is inhibited for a fixed time after an AC power
failure. The delayed start is required to allow time for the batteries to be
sufficiently charged, in order that the required total AC input current for the
two rectifiers be reduced to less than 20 amperes.
The rectifier that is delayed will be activated immediately if the main rectifier
fails, is pulled out or missing, or produces an RFA. The delayed start rectifier
will not transmit an RFA signal to the Controller during the time that it is
inhibited, but it will permit transmission of an RFA signal to the Controller
after the delayed start period.
When the rectifier is on the delayed start mode, the RFA LED on the
rectifier will be lit (red), and the "DELAYED START" yellow LED of the
timer will be ON to indicate that the rectifier with the red RFA LED is on
delayed start mode.
25A Switch Mode RectifierNT5C06B / C Installation and User Manual

Power-up and verification
Verification
For systems equipped with the NT5C10CO power shelf, proceed as
indicated in Procedure 22.
Procedure 22 - Power-up and verification
Step
Action
1
Verify that the AC circuit breakers of the rectifiers are in the “OFF”
position.
2
Release the clamping bar of the power shelf, by loosening the two
retaining screws.
3
Remove the right blank panel from the power shelf by removing the
retaining screw, pushing it up and pulling it out.
4
Locate the timer switch SW1 (located on the circuit pack at the right side
of the power shelf) and verify the settings. Default factory settings
should be as follows (24-hour delay):
Plug the AC power plug into the wall receptacle.
Turn “ON” the AC circuit breakers of the main rectifier. Verify that the
DELAYED START yellow LED is lit.
Verify the main rectifier voltage and set the voltage limits as specified by
the system and the manufacturer of the battery by referring to the
“Start-up procedure” section found in the “Installation and start-up
procedure” chapter of this manual.
The “Delayed Start” rectifier must be adjusted to the same voltages as
the main rectifier. To do so, turn OFF the main rectifier and turn “ON” the
AC breaker of the delayed rectifier. Repeat Step 6 & 7 on the unadjusted
rectifier.
Turn on the DC breaker of the main rectifier.
Wait until the delayed start yellow LED is extinguished (12h or 24h) OR
until the system batteries are fully charged to their nominal voltage
before proceeding to the next procedure: “Adjustment and verification”.

The above settings will provide a delay of approximately 24 hours, which is
sufficient to charge the batteries with a reserve of 80 to 120AH, and at the
same time supply power to a 10 A load. When the load is 6 A, or less on a
battery reserve of less than 80AH, open the SW1-4 and close the SW1-3 for a
delay of 12 hours.
Adjustment and verification
The following steps are required to verify the system’s operation.
CAUTION
The power system batteries must be fully charged to their
nominal voltage before proceeding with the following steps.
Procedure 23 - Adjustment and verification

The above settings will provide a delay of approximately 24 hours, which is
sufficient to charge the batteries with a reserve of 80 to 120AH and at the
same time supply power to a 10 A load. When the load is 6 A, or less on a
battery reserve of less than 80AH, open SW1-4 and close SW1-3 for a delay
of 12 hours.
