Requirements for the Supplying Source
In certain circumstances, the input filter of the DC/DC converter can show a
resonant effect, which is caused by the supplying network. When additional
external input filters are used, a superimposed AC voltage can be generated on
the input terminals of the DC/DC converter, which might cause a unit
malfunction. Therefore, additional input filters are not recommended. To
avoid the resonant effects, the minimal resistance of the supplying network
that depends on the inductance of the input network, must be above the
boundary curve in Figure 4.

Input Inrush Current
A negative temperature coefficient (NTC) resistor limits the input inrush
current after turn-on of the input voltage. The inrush current is dependent on
input voltage and ambient temperature. The output load has no impact on the
inrush current value.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.

After the DC/DC converter is turned on, the internal output current rises
slowly to its nominal value. This method charges the output capacitors
(internal and external capacitors) slowly and avoids high input currents
during turn-on. High input currents can produce a high-voltage drop on the
input wiring (especially with long and thin cables) which reduces the terminal
voltage on the DC/DC converter. If the terminal voltage is below the shutdown
voltage, the DC/DC converter will turn-off and will make a new startup
attempt. This effect is avoided with the integrated soft start function. Please
note that this function increases the rise time of the output voltage by a small
amount.
The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage and is designed to supply any kind of loads, including
unlimited capacitive and inductive loads.
The output is electronically protected against overload, no-load, and shortcircuits. If there is a protection event, an audible noise can occur.

The input side of the DC/DC converter is equipped with a bulk capacitor that
keeps the output voltage alive for a certain time period when the input voltage
dips or is removed. The bulk capacitor can be discharged by loading the DC/DC
converter on the output side or through a load that is parallel to the input.
There is no protection in the DC/DC converter that helps prevent current from
flowing back to the input terminals. If prevention is needed, use an external
diode.
At no load, the hold-up time can be up to several seconds. During this time, the
green DC-OK lamp is also on.

Daisy Chaining of Outputs
Daisy chaining (jumping from one DC/DC-converter output to the next) is
permitted, as long as the average output current through one terminal pin
does not exceed 25 A. If the current is higher, use a separate distribution
terminal block.

The Lifetime expectancy that is shown in the table indicates the minimum
operating hours (service life) and is determined by the lifetime expectancy of
the built-in electrolytic capacitors. Lifetime expectancy is specified in
operational hours and is calculated according to the capacitor’s manufacturer
specification.
The manufacturer of the electrolytic capacitors only states a maximum life of
up to 15 years (131,400 hr). Any number that exceeds this value is a calculated
theoretical lifetime, which can be used to compare devices.

Mean time between failure (MTBF) is calculated according to statistical device
failures, and indicates reliability of a device. The MTBF value is a statistical
representation of the likelihood of a unit to fail and does not necessarily
represent the life of a product. An MTBF value of, for example, 1,000,000 hr
means that statistically one unit fails every 100 hours if 10,000 units are
installed in the field. However, it cannot be determined if the failed unit has
been running for 50,000 hr or only for 100 hr.
For these types of units, the Mean Time to Failure (MTTF) value is the same as
the MTBF value.

The leakage current, which is produced by the DC/DC converter itself, depends
on the input voltage ripple and must be investigated in the final application.
For a smooth DC input voltage, the produced leakage current is <100 µA.
The output voltage is floating and has no ohmic connection to the ground.
Double or reinforced insulation insulates the output to the input.
It is recommended that either the + pole or the – pole be connected to the
protective earth (PE) system. This helps to avoid situations in which a load
starts unexpectedly or cannot be switched off when unnoticed earth faults
occur.
The manufacturer conducts type and routine tests. Field tests can be
conducted in the field with the appropriate test equipment, which applies the
voltage with a slow ramp (2 seconds [s] up and 2 seconds down). Connect all
phase-terminals together and all output poles before conducting the test.

48V DC Redundancy Module (Cat. No. 1606-XLERED)
This dual redundancy module can be used to build 1+1 or N+1
redundant systems.
The device is equipped with two input channels, each 10 A
nominal, which are individually decoupled by using diode
technology. The output can be loaded with nominal 20 A.
The device does not require an additional auxiliary voltage and
is self-powered, even in case of a short circuit across the output.
The device has a monitoring circuit included and is the perfect
choice when the power supply has no DC-OK function. Two
light-emitting diode (LEDs) and two relay contacts signal when
one of the two input voltages is not in range due to a nonfunctioning or disconnected power supply.
1606-XLERED
The unit is slender and only requires 32 mm (1.26 in.) width on the
DIN rail.
Buffer Module (Cat. No. 1606-XLSBUFFER)
This buffer module is a supplementary device for 48V
DC/DC converters. It delivers power to bridge typical
supply voltage faults or extends the hold-up time after
turn-off of the input power.
In times when the DC/DC converter provides
sufficient voltages, the buffer module stores energy in
integrated electrolytic capacitors. If there is a supply
voltage fault, then this energy is released again in a
regulated process.
1606-XLSBUFFER
18
Rockwell Automation Publication 1606-RM124A-EN-P - September 2021
DC/DC Converter - 48V/48V, 5 A, 240 W Reference Manual
The buffer module does not require any control wiring. It can be added in
parallel to the load circuit at any given point.
One buffer module can deliver 20 A additional current. Buffer modules can be
added in parallel to increase the output ampacity or the hold-up time.
Peak Current Capability
The unit can deliver peak currents (up to several milliseconds), which are
higher than the specified short-term currents.
This capability helps to start current-demanding loads. Solenoids, contactors,
and pneumatic modules often have a steady state coil and a pick-up coil. The
inrush current demand of the pick-up coil is several times higher than the
steady-state current and usually exceeds the nominal output current. The
same situation applies when starting a capacitive load.
The peak current capability also achieves the safe operation of subsequent
circuit breakers of load circuits. The load branches are often individually
protected with circuit breakers or fuses. If there is a short or an overload in one
branch circuit, the fuse or circuit breaker need a certain amount of overcurrent
to open in a timely manner. This avoids voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the
built-in large sized output capacitors of the power supply. The capacitors get
discharged during such an event, which causes a voltage dip on the output.
Figure 24 and Figure 25 show two typical voltage dips.

Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are
commonly used for AC-supply systems and can also be used on 48V branches.
MCBs are designed to protect wires and circuits. If the ampere value and the
characteristics of the MCB are adapted to the wire size that is used, the wiring
is considered as thermally safe, regardless of whether the MCB opens or not.
To avoid voltage dips and undervoltage situations in adjacent 24V branches
that are supplied by the same source, a fast (magnetic) tripping of the MCB is
desired. A quick shutdown within 10 ms is necessary, corresponding roughly to
the ride-through time of programmable logic controllers (PLCs). This
shutdown requires power supplies with high current reserves and large output
capacitors. Furthermore, the impedance of the faulty branch must be
sufficiently small for the current to flow. The best current reserve in the power
supply does not help if Ohm’s Law does not permit current flow. The following
table has typical test results showing which B- and C-Characteristic MCB’s
magnetically trip depending on the wire cross section and wire length.

The device can be used to charge lead-acid or maintenance free batteries. Four
12V SLA or VLRA batteries are needed in series connection.
IMPORTANT
Use only matched batteries when putting 12V types in series.
Do not use the device for battery charging in mounting orientations other
than the standard mounting orientation, or in any other condition where a
reduction of the output current is required (for example, altitude).
To charge batteries, perform the following steps.
1. Verify that the ambient temperature of the device is below 45 °C (113 °F).
2. Set the output voltage, which is measured at no load and at the battery
end of the cable, precisely to the end-of-charge voltage.

3. Use a 10 A circuit breaker or blocking diode between the device and the
battery.
4. Verify that the output current of the device is below the allowed charging
current of the battery.
The return current to the device (battery discharge current) is typically
6 mA when the device is switched off (except when a blocking diode is used).
Series Operation
Devices of the same type can be connected in series for higher output voltages.
You can connect as many units in series as needed, if the sum of the output
voltage does not exceed 150V DC. Voltages with a potential above 60V DC must
be installed with protection against touching.
Avoid return voltage (for example, from a
decelerating motor or battery) that is
applied to the output terminals.

conditions on all devices, or the devices can be left with the factory settings.
The ambient temperature cannot exceed
45 °C (113 °F).
If more than three devices are connected

Parallel Use for Redundancy
These devices can be parallel used for two types of redundancy. For a wiring
example of either redundancy configuration, see Figure 26 and Figure 27, both
on page 22.
1+1 Redundancy
Devices can be paralleled for 1+1 redundancy to gain higher system availability.
Redundant systems require a certain amount of extra power to support the
load in case one device fails. The simplest way is to put two devices in parallel.
This is called a 1+1 redundancy. In case one device fails, the other one is
automatically able to support the load current without any interruption. It is
essential to use a redundancy module to decouple devices from each other.
This redundancy helps prevent the defective unit from becoming a load for the
other device, which helps confirm that the output voltage can be maintained.
EMI and inrush current increase when you use multiple devices.
The following recommendations are for building 1+1 redundant power systems:
• Whenever possible, use separate supply systems for each device.
• Monitor the outputs of each device. Use the DC-OK lamp or the DC-OK
contact, which are included in the Cat. No. 1606-XLERED Redundancy
Module.
• Set the output voltages of all devices to the same value (± 100 mV), or
leave them at the factory setting.
• The ambient temperature cannot exceed 70 °C (158 °F).
N+1 Redundancy
Redundant systems for a higher power demand are built in an N+1 method,
such as four devices with each rated for 10 A are paralleled to build a 30 A
redundant system.
EMI and inrush current increase when you use multiple devices.

The following recommendations are for building N+1 redundant power systems:
• Keep a left/right installation clearance of 15 mm (0.6 in.) between two
devices, and do not install the devices on top of each other.
• Do not use devices in parallel in mounting orientations other than the
standard mounting orientation or in any other condition, where a
reduction of the output current is required.
• The ambient temperature cannot exceed 45 °C (113 °F).

When the device is installed in a tightly sealed enclosure, the temperature
inside the enclosure is higher than outside. In such situations, the inside
temperature defines the ambient temperature for the device.
In the following test setup, the device is placed in the middle of the enclosure,
and no other heat-producing items are inside the enclosure. The load is placed
outside the enclosure.
The temperature sensor inside the box is placed in the middle of the right side
of the DC/DC converter with a distance of 1 cm (0.39 in.). The following
measurement results can be used as a reference to estimate the temperature
rise inside the enclosure.

Mounting orientations other than input terminals on the bottom and output
on the top require a reduction in continuous output power or a limitation in
the maximum allowed ambient temperature.
The listed lifetime and MTBF values from this data sheet apply only for the
standard mounting orientation.
The following curves indicate the allowed output currents for altitudes up to
2000 m (6562 ft).
