All payments shall be made in U.S. Dollars.
5.
DELIVERY; CANCELLATION OR CHANGES BY BUYER.
Unless
otherwise stated on the face hereof, delivery shall be F.O.B. Seller's facility. Unless
otherwise mutually agreed to by the parties, Seller will select the carrier for shipment of
the Products, but in no event will Seller be deemed to assume any liability in connection
with such shipment nor will the carrier be deemed to be the agent of Seller. Seller
reserves the right without penalty to deliver prior to requested delivery dates and to
deliver in installments, each to be separately invoiced and paid when due without regard
to subsequent deliveries. The Products will be insured in transit at the expense of Buyer.
Seller reserves the right to stop delivery of Products in transit and to withhold shipments
in whole or in part if Buyer fails to make any payment to Seller when due or otherwise
fails to perform its obligations hereunder. All delivery dates are estimates. SELLER
SHALL NOT BE LIABLE FOR ANY LOSSES, DAMAGES OR PENALTIES IF
ESTIMATED SHIPPING OR DELIVERY DATES ARE NOT MET. In the event of
a delay due to any cause beyond Seller's reasonable control, Seller reserves the right to
terminate the order or to reschedule the shipment within a reasonable period of time, and
Buyer will not be entitled to refuse delivery or otherwise be relieved of any obligations as
the result of such delay. Products as to which delivery is delayed due to any cause within
Buyer's control may be placed in storage by Seller at Buyer's risk and expense and for
Buyer's account. Orders in process may not be cancelled, either in whole or in part,
without Seller's written consent, and then only under terms that will reimburse Seller for
all applicable costs incurred by it, including but not limited to the costs of purchased
materials and a reasonable allowance for profit. Orders in process may not be changed
except with Seller's written consent and upon agreement by the parties as to an
appropriate adjustment in the purchase price therefor. Credit will not be allowed for
Products returned without the prior written consent of Seller.
6.
TITLE AND RISK OF LOSS. Subject to the provisions of Section 7 below
and to Seller's right to stop delivery of Products in transit, title to and risk of loss of the
Products will pass to Buyer upon delivery of possession of the Products by Seller to the
carrier; provided, however, that title to any software incorporated within or forming a part
of the Products shall at all times remain with Seller or the licensor(s) thereof, as the case
may be. Any claims for damage to, or loss or mis-delivery of, the Products will be filed
Document: MAN00238A
directly with the carrier by Buyer. Buyer shall inspect products immediately upon
receipt, notify Seller in writing of any claims for shortages, defects or damages and hold
the damaged or defective products for Seller's written instructions concerning disposition.
If Buyer fails to so notify Seller within 30 days after the goods have been received by
Buyer, the goods shall conclusively be deemed to conform to the terms, conditions and
specifications hereunder and to have been accepted by Buyer. Goods returned prior to
receiving shipping instructions from Seller or which do not conform to such instructions
are at Buyer's sole risk and expense. Seller shall have the right to cure the tender of
damaged or defective goods by substituting a conforming tender within a reasonable time.
7.
SECURITY INTEREST.
Seller reserves and Buyer grants to Seller a
security interest in all Products sold and all proceeds thereof to secure the full payment
and performance by Buyer of its obligations and liabilities to Seller. Buyer acknowledges
and agrees that this document or copies of this document may be filed with the
appropriate authorities as a financing statement and agrees to execute and deliver such
other documents as Seller may request in order to evidence or perfect such security
i n t eres t .
8.
FORCE MAJEURE. Seller shall not be responsible for delays or failures in
performance and shall have no liability to Buyer resulting from causes beyond its
reasonable control. Causes beyond Seller's reasonable control include but shall not be
limited to acts of God, epidemics, earthquakes, unusually severe weather, floods or other
natural disasters, war, riot, fire, accident, explosion, strikes or other labor trouble,
government acts or omissions, delay or default by subcontractors or suppliers of materials
or services, transportation difficulty or shortages in labor, fuel, materials, supplies or
power at current prices (the "Force Major Event").If Seller is unable because of a Force
Major event to supply the total quantity of goods specified in Buyer's order, Seller may
allocate its available supply among any or all of its buyers on such basis as Seller may
deem commercially fair and practical, without liability for any failure of performance
which may result therefrom.
9.
PACKING, STORAGE AND SPECIAL SERVICES Prices do not include
storage, packing or cartage service. Storage for any reason, including a Force Major
Event, shall be at Buyer's risk and expense.
10.
CHANGES. Buyer may make a written request for changes in drawings,
designs or specifications for the goods, but acceptance of any requested change shall be at
Seller's sole discretion, must be in writing and shall be upon such terms and conditions as
Seller may require. If any such change causes an increase or decrease in the cost of or in
the time required for performance, an equitable adjustment shall be made and the contract
modified accordingly.
11.

1. INTRODUCTION
This high voltage power supply incorporates the latest in high frequency, high power switching
technology. Each unit is neatly packaged in a single, rack-mountable chassis with approximate
dimensions of 10.5" high X 19" wide (maximum) X 21" deep (approximately 2 additional inches are
required behind the chassis for connections).
Operation of the power supply can be accomplished locally via the front panel controls and/or
remotely via the rear panel User Interface connector J4. Certain commands or signals are operative
in both modes. For example, the local HV OFF pushbutton switch is operative in both Local and
Remote modes. Refer to Section 5, "User Interface", for details.
The polarity of the output is adjustable, however each unit is shipped from the factory in negative
output mode. The output polarity can be altered by changing the position of the output polarity
plate.

2. WARNINGS
DANGER
HIGH VOLTAGE
RISK OF ELECTRICAL SHOCK
REFER SERVICING TO QUALIFIED PERSONNEL
This power supply operates at a high enough voltage and possesses
sufficient stored energy to be capable of killing a human.
DO NOT TAKE SAFETY FOR GRANTED!
Pay strict attention to the safety information and warnings in this manual.
This power supply produces extremely high voltages. DO NOT attempt to adjust any load
connection with high voltage on. DO NOT attempt to open the power supply enclosure unless the
manual has been thoroughly reviewed and the internal layout is understood. Never reach into the
enclosure unless the power has been disconnected and the output is fully discharged. Be certain of
safety ground connections.
Assuming that high voltage is always ON is the best way to avoid hazard to personnel. Always shut
off the supply circuit breaker(s) and follow an appropriate grounding procedure to discharge the
output before touching any exposed connections.
DO NOT rely on the power supply’s instrumentation or controls to determine that the output is
safely discharged. The sensors are driven by amplifiers, which are powered by an internal low
voltage power supply, as are the indicator LEDs. There may be dangerous voltages present on the
output, even if the unit appears "dead".
If not manually discharged, the output may remain charged long after power is disconnected!
DO NOT allow anyone who has not reviewed the manual to perform any part of the installation
process or to attempt servicing of the power supply. Any questions must be brought to the attention
of the manufacturer.
DO NOT obstruct the cooling inlets or outlets. Overheating can result, which may damage the
power supply.

3. UNPACKING
Remove the unit from its carton, but do not discard the packing materials; retain the packing
materials and carton in case the unit needs to be returned.
Inspect the unit for dents or other damage, which may have occurred during shipping. In the unusual
event that shipment damage has occurred, contact the transportation company and the manufacturer
immediately.
If additional materials have been enclosed in the shipping crate (such as cables etc.), inspect them as
well. Put them aside and DO NOT proceed until this instruction manual has been thoroughly
reviewed.

4. INSTALLATION
Symbol Definitions
Protective Conductor Terminal
Indicates where to connect safety ground conductor from AC line source.
Caution: Risk of Electric Shock
Indicates that high voltages, capable of causing injury, are present on the output
connector.
Caution: Refer to Manual for Further Instructions
Directs user to manual for further detailed instructions on installation and operation.
Refer to Section 2 of this manual.
Input Voltage Selection
Before the BRC power supply may be installed, it is critical that the AC line voltage being connected
to the unit fits within the specifications below:
208VAC ±10% (187-229 VAC), 3-phase
The power supply does not require an electrical neutral. The unit is not sensitive to phase rotation.
Double check your power wiring before proceeding with the installation.
CAUTION
Chassis supports must not block air passages located on the unit’s side panels. A fan located on the
left side panel pulls air in through a heatsink located on the right side panel.
1. Turn OFF the front panel circuit breaker.
2. Connect the ground stud on the rear panel of the chassis to a suitable building or system ground,
and to the low end of the output load(s). Use a 0.5 inch (~1.3 cm) wide metal earthling braid or #6
AWG UL1015 insulated stranded wire with properly crimped ring terminals where required.
Heavier conductors may be used. The ground stud on the rear panel should be the common point
of all ground connections.
3. Terminate the high voltage output cable to the high end of the load. Make sure it is tightly
fastened.
4. It is good practice to keep the high voltage (HV) cable away from sharp objects, machinery, and
high traffic areas. This will minimize the possibility of damage to the cable.
5. Ensure the Local/Remote switch on the rear panel is set to the proper mode of operation, either
local or remote, as described in Section 5.
Document: MAN00238A
Page 10 of 28
R:\Documents\MAN Manuals\MAN00238A BRC-15-1111R-STD-J37.doc
6. Connect remote control circuitry (if used) to the rear panel connector, J4, as described in Section 5.
7. With the breaker in the OFF position and the building power OFF, connect AC power lines to the
unit. It is very important to use 600V (UL1015) insulated stranded wire of sufficient gauge (#6
AWG or greater) to handle the full load line current. Strip about 0.4 inch (~1 cm) of insulation
from the wires before inserting them into the terminal block.
Phase sequence is not critical on this three phase switching power supply.
8. When all of the connections have been double checked, apply AC power from the source circuit
breaker box and turn the front panel circuit breaker ON. The unit is now ready for high voltage
operation.

5. USER INTERFACE
Operation of the User (Remote) Interface is essentially equivalent to the local front panel controls.
Each unit has been shipped from the factory in Remote mode. To change to Local mode operation,
use the Local/Remote switch located on the rear panel. See Figure 1 for an illustration of the
Local/Remote switch and the Regulator connector located on the rear panel.
Functions that are underlined are operational in both Local and Remote modes. In addition, please
note that the local HV OFF switch is operational in both Local and Remote modes for safety reasons.

Analog Voltage Monitor (Output):
This low impedance output should be connected to a high impedance load. A typical load would be
a voltmeter or the analog input of a computer interface. A micrometer or millimeter, in series with
an appropriate resistor, will function well. It is best if the resistor is adjustable so that the meter
calibration may be trimmed. Zero to +10V on this pin represents zero to -15.0kV HV output (0 to
+10V = 0 to -15.0kV). The source impedance for this signal is 1k ohm.

Connect to negative terminal of meters or return of other measurement instrument applied to pins 4

7, 8. High Voltage OFF Control (Input):
Connect to a normally closed (NC) set of isolated ("voltage free" or "dry") switch contacts.
Operation of these contacts must be momentary (i.e. the contacts stay closed until the switch is
operated, at which time they open briefly, and the contacts automatically return to the closed state
after an operation).
9, 10.
External Interlock (Input):
Short these pins together to complete interlock loop.
11, 12.
High Voltage ON Control (Input):
Connect to a normally open (NO) set of isolated switch contacts. Operation of these contacts
should be momentary, but an alternate action switch is acceptable.
13.
Remote HV ON Monitor (Output):
This signal is +5VDC when HV is ON and is +0VDC when HV is OFF.
14.
Common Pin for High Voltage ON Control and Inhibit Command (Input):
Connect to return for Remote HV ON Monitor and Inhibit Command signals.
15.
Inhibit Command (Input):
This input is used to prevent high voltage from being turned on in any mode of operation. By
maintaining +5VDC on this pin (TTL high state), high voltage is prevented from being turned on
by the front panel pushbutton or the User Interface, and will terminate high voltage if in the ON
state.

Regulator 9120010
The regulator circuit receives the two reference voltages (0 - 10V), as set by the remote references or
by the front panel voltage and current pots, R1 and R2, respectively. See Figure 2. These reference
voltages feed the KV error amplifier and mA error amplifier. The objective of each error amplifier is
to make the feedback signal equal to the reference signal. The pulse width modulator chip generates
the main switching frequency (approximately 22kHz).

Power Card 853189539P
AC power is connected to a three phase bridge rectifier circuit. See Figure 3. The rectifiers power a
raw capacitive filter. The inverter switches, in a full bridge configuration, alternate the high voltage
transformer primary winding between the rail voltages established by the raw supply capacitors,
producing a bipolar square wave signal on the primary winding.

Figure 3 – Power Inverter Simplified Diagram
The inverter switches are IGBTs that are gated ‘ON’ for an interval established by the pulse width
modulator chip on the Regulator card. At power turn-on, the raw capacitor bank is charged through
rectifier CR12 and current limited by R42 and R43. When the initial charge period is complete,
relay K1 is energized, connecting the rail capacitors to the low impedance three-phase line.
The inverter IGBTs do not operate until the raw capacitors are charged, K1 is energized, and the
‘HV ON’ pushbutton is depressed. The IGBT gate signal originates on the Regulator board as
varying width pulses at a fixed frequency. The frequency is determined by R219 and C133 on the
Regulator board.

7. HIGH VOLTAGE ON
Once the installation is complete, the power supply is ready to be energized. Turn on the system
power at the source circuit breaker box. To activate the control electronics, switch the front panel
breaker to the ON position. The ‘Power On’ indicator will be illuminated.
Local Mode
High voltage can be activated if all interlocks and faults are clear. To enable high voltage, press the
‘HV ON’ pushbutton. The white ‘HV ON’ light will illuminate indicating that there is high voltage
on the output. To turn the supply off, press the ‘HV OFF’ pushbutton. This will disable high
voltage and clear any faults.
The ‘kV Adjust’ knob and the ‘A Adjust’ knob must both be above zero to allow the power supply
to produce any output voltage or current. 3½ digit panel meters for output voltage and current have
been provided on the front panel. They facilitate easy interpretation of the output values at a glance.
LEDs below the front panel LCD displays indicate the mode of control, voltage regulation or current
regulation.
Remote Mode
If all interlocks and faults are clear, the User Interface can now be used to activate and control the
high voltage output. Refer to Section 5 for User Interface control details.

9. CIRCUIT BOARD ADJUSTMENTS
Although each power supply is fully tested and calibrated prior to shipment, there are circuit boards
in the unit that may require adjustment at some time during the life of the power supply. These
boards are the Regulator board (9120010) and Front Panel board (9120021).
Before attempting to make any adjustments inside the power supply chassis, please be sure that the
consequences of such an adjustment are completely understood.
Do not attempt to make any adjustment unless you fully understand the function of each
potentiometer. These adjustments are preset by the manufacturer and should not be disturbed unless
you are experiencing difficulties.
Refer to Figures 4 and 5 for the exact locations of adjustment potentiometers on the circuit boards
(PWAs) listed above. Also refer to the list on the following page, which will describe the function
of each potentiometer in detail.
For a detailed description of adjustment procedures, see the Acceptance Test Procedure called out in
Section 13.

Iavg OL Adjust: sets the sensitivity of the HV transformer’s average
primary current limit circuit. This protects the power inverter from
large values of average current over a period of many inverter
cycles. This circuit does not protect against high peaks of
instantaneous current.
Counter Adjust: sets the sensitivity of the arc counter circuitry which
shuts off high voltage if too many arcs or rollbacks occur in a given
period of time. It also functions as an arc rate circuit, since a rapid
succession of arcs is more apt to trip the circuit than the same
number of arcs spread out over a longer period of time.
Rail Fault Adjust: sets the trip point of a circuit which is sensitive to
excessive current in the power inverter. This type of fault could
indicate that an IGBT in the inverter has failed. This circuit has a
purpose similar, but not identical, to the “Iavg OL” circuit.
However, the rail fault circuit protects against more catastrophic
events, especially faults occurring within the inverter itself. It is a
latched fault, requiring a reapplication of ‘HV ON’ to resume HV
operation. DO NOT retry ‘HV ON’ more than once or twice after a
rail fault occurs, since this indicates damage has occurred within the
inverter and further attempts to turn on HV may worsen the damage.
Slow OC Adjust: sets the trip point of the slow responding overload
circuit, which monitors the output current. This circuit terminates
HV if the load demands an excessive amount of average current. It
is a latched fault, requiring a reapplication of ‘HV ON’ to resume
HV operation. (This circuit is normally set to approximately 5%
above the rated maximum load current). This circuit would function
well during an excessive increase in load which might not be
detected by the other protection circuitry.
OV Adjust: sets the threshold of the overvoltage circuitry, which
monitors the output voltage. This circuit terminates HV if it detects
voltage higher than the set point. The set point is factory adjusted to
5% above the maximum rating of the supply.
+10V Ref Adjust: calibrates the precision internal reference voltage
to +10.000V.

10. FAULTS / TROUBLESHOOTING
Faults
Overcurrent: If the output becomes shorted or if there is a surge in output current due to changes in
the load that exceed the rated current, then this circuit will be tripped. Its threshold is
set by R137. Once this circuit is tripped, HV is latched off. The power supply will
give a fault indication by lighting the ‘Fault’ LED permanently. The ‘HV ON’ light
will go out as well. This tells the user to correct the load and reactivate HV.
Both overload (or overcurrent) circuits are driven by a buffered current feedback
signal that is derived from a shunt resistor located in the high voltage section of the
power supply.
Overvoltage: Overvoltage is a fault which will rarely be tripped. Adjustable via R69, this circuit
will be activated when it senses output voltage which is greater than the set point. An
unstable system, due to load dynamics, may cause an overvoltage condition. This
circuit is driven by a buffered voltage feedback signal derived from the HV divider.
This fault will cause HV to be latched off and the Fault LED will light.
dV/dt:
(Change in Voltage per Change in Time) The source of a fault of this type is an
output arc, which causes a very large change in voltage in a short period of time.
This circuit is also driven by the voltage feedback. Like the fast OL fault, this type of
fault causes a rollback, which will not place the supply in a latched fault condition. It
merely temporarily interrupts high voltage so the condition can clear. The output
then recovers to the set point with little indication. The purpose for this type of
recovery is that permanent shutdowns or faults can become a nuisance when arcing is
a common occurrence in high voltage systems.
The dV/dt circuit is not adjustable.
AC Overload: The AC OL fault is the average primary current or "Avg OL" fault, which is more
sensitive when the unit is operating closer to its rated output voltage and current. It is
a slower responding circuit than the peak circuit and its main purpose is to limit
power output by triggering rollbacks. Sensitivity is adjusted via R41.
The AC OL fault circuits are non-latching. They act to keep the primary current in
the HV transformer from reaching excessive levels.
Rail Fault:
This circuit protects against excessively large current in the power inverter, which
may or may not be related to the primary current signal. However, the rail fault
circuit is used to protect against more catastrophic events than the typical output
conditions the primary current circuits were designed to withstand.
An imbalance in the voltage sharing of the power switches or a failed power switch
might be the cause of a rail fault. Thus, you will rarely (if ever) see this type of
latched fault. Like the other latched faults, this circuit will illuminate the Fault LED.
The sensitivity of this circuit is adjustable via R165.

Page 24 of 28
R:\Documents\MAN Manuals\MAN00238A BRC-15-1111R-STD-J37.doc
Rollbacks and the One-Shot Timer
As discussed previously, a rollback is distinct from a latched fault in that it does not shut high
voltage off permanently. A latched fault requires that an HV ON command be given again before
HV can be reactivated.
The non-latched circuits cause a brief rollback (or limiting action). This is the case for the fast
overload, dV/dt, peak primary current overload, and the average primary current overload circuits.
These circuits feed an additional circuit which controls the duration of time that the shutdown
condition is permitted to be present. This circuit is called the rollback timer and its duration (called
the rollback period) is adjustable via R9 on the front panel PCB. The rollback timer setting is one of
the key ingredients to arc recovery performance and is critical in many applications.
The one-shot period must be long enough to allow an output arc to extinguish before the power
supply begins to make output again. It should also allow sufficient time for the related electronics to
be "reset" or return to their nominal state. On the other hand, it must not be too long as to cause
operational difficulties.
Therefore, if problems are encountered which appear to be related to arc recovery, this potentiometer
behind the front panel may be adjusted until the desired performance is achieved. To see the effect
of this adjustment directly, it is helpful to use a storage oscilloscope to view the voltage monitor
output on the rear panel (J4, pin 4) while rollbacks are occurring. You can induce a rollback by
striking the output with a ground stick. As the rollback period is adjusted, you will see the off time
of the power supply vary. The off time begins the instant a rollback event occurs and ends at the
instant the output starts to rise again.
