Product Overview
Bulletin 1606-XLE power supplies are cost optimized without compromising
quality, reliability, and performance. Bulletin XLE power supplies offer high
efficiency, electronic inrush current limitation, active Power Factor Correction
(PFC), and wide operational temperature range. The compact size is achieved
using synchronous rectification, LLC technology, and other design details.
The 1606-XLE480FP includes all essential basic functions. The device has a
power reserve of 20% included, which can be used continuously at
temperatures up to 45 °C (113 °F). The 1606-XLE480FP can deliver about three
times the nominal output current for 12 ms, which helps to trip fuses on faulty
output branches.
The 1606-XLE480FP is suitable for a wide variety of applications because of its
high immunity to transients and power surges, low electromagnetic emission,
DC OK relay contact, and large international approval package.

Output
The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage.
The device is designed to supply any kind of loads, including capacitive and
inductive loads. If large capacitors, such as electric double layer capacitors
(EDLCs or UltraCaps) with a capacitance > 0.25 F are connected to the output,
the unit might charge the capacitor in an intermittent mode.
The output is electronically protected against overload, no-load, and
short-circuits. If there is a protection event, audible noise can occur.

(1) This current is also available for temperatures up to 70 °C (158 °F) with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
(2) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2 s. After this, the output is switched off
for 18 s approx before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been
cleared, the device operates normally. See Figure 9 on page 10.

“Parallel Use” “Single Use” Link
Link the two terminal poles when power supplies are connected
in parallel to increase the output power. To achieve a sharing of
the load current between the individual power supplies, the
“parallel use” regulates the output voltage in such a manner
that the voltage at no load is approx 4% higher than at nominal
load. See Parallel Use to Increase Output Power on page 27.

Lifetime Expectancy
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 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. An MTBF value is a
statistical representation of the likelihood of a device 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
value as the MTBF value.

Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
A double or reinforced insulation insulates the output to the input.
The manufacturer conducts type and routine tests. Field tests can be
conducted in the field using the appropriate test equipment, which applies the
voltage with a slow ramp (2 s up and 2 s down). Connect all input-terminals
together as well as all output poles before conducting the test. When testing,
set the cutoff current settings to the value in the table below.
We recommend that you connect either the + pole or the – pole to the
protective earth system. This helps to avoid situations in which a load starts
unexpectedly or cannot be switched off when unnoticed earth faults occur.

1606-XLSBUFFER48 Buffer Module
The 1606-XLSBUFFER48 buffer module is a supplementary device for DC 48V
power supplies. It delivers power to bridge typical mains failures or extends
the hold-up time after the AC power is turned off.
When the power supply provides a sufficient voltage, the buffer module stores
energy in the integrated electrolytic capacitors. When the mains voltage is lost,
the stored energy is released to the DC-bus in a regulated process.
The buffer module can be added in parallel to the load circuit at any given
point and does not require any control wiring.
One buffer module can deliver 20 A additional current and can be added in
parallel to increase the output ampacity or the hold-up time.
1606-XLSRED40HF Dual Redundancy Module
The 1606-XLSRED40HF is a dual redundancy module, which can be used to
build 1+1 or N+1 redundant systems.
The device is equipped with two 20 A nominal input channels, which are
individually decoupled using MOSFET technology. The output can be loaded
with a nominal 40 A continuous current.
Using MOSFETs instead of diodes reduces heat generation, losses, and voltage
drop between input and output. Due to these advantages, the unit is narrow
and only requires 46 mm (1.81 in.) width on the DIN rail.
The device does not require an additional auxiliary voltage and is self-powered
even if there is a short circuit across the output. It requires suitable power
supplies on the input, where the sum of the continuous short circuit current
stays below 45 A. This is typically achieved when the power supplies are
featured with an intermittent overload behavior (Hiccup Mode).
See Parallel Use for Redundancy on page 28 for wiring information.

Peak Current Capability
The unit can deliver peak currents (up to several milliseconds) which are
higher than the specified short-term currents.
Peak current capability helps to start load that have a high demand for current.
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.
Peak current capability also helps achieve 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. The
following three examples show typical voltage dips for resistive loads.

Output Circuit Breakers
Standard miniature circuit breakers (MCBs or UL 1077 circuit breakers) are
commonly used for AC-supply systems and can also be used on 48V branches.
MCBs are designed to help 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 PLCs. This requires power supplies with high current
reserves and large output capacitors. Furthermore, the impedance of the faulty
branch must be sufficiently small in order 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 MCBs magnetically trip depending on the wire cross section
and wire length.
The following table of test results shows the maximal wire length for a fast
(magnetic) tripping. The wire length is always two times the distance to the
load (+ and – wire).

Charging of Batteries
The power supply can be used to charge lead-acid or maintenance free
batteries. Four 12V SLA or VRLA batteries are needed in series connection.
Instructions for charging batteries:
1. Use only matched batteries when putting 12V types in series.
2. Ensure that the ambient temperature of the power supply stays below
40 °C (104 °F).
3. Use a 15 A or 16 A circuit breaker or a blocking diode between the power
supply and the battery.
4. Ensure that the output current of the power supply is below the allowed
charging current of the battery.
5. The return current to the power supply is typically 6 mA. This return
current can discharge the battery when the power supply is switched off
except in case a blocking diode is used.
6. Set the device to Parallel Use mode. Adjust the output voltage precisely to
the end-of-charge voltage, measured at no load and at the battery end of
the cable.

Devices of the same type can be connected in series for higher output voltages.
It is possible to connect as many units in series as needed, providing the sum
of the output voltage does not exceed 150V DC. Voltages with a potential above
60V DC must be installed with a protection against touching.
Avoid return voltage (for example, from a decelerating motor or battery) which
is applied to the output terminals.
Keep an installation clearance of 15 mm (0.59 in.) (left / right) between two
power supplies and avoid installing the power supplies on top of each other.
Do not use power supplies in series in mounting orientations other than the
standard mounting orientation.
Leakage current, EMI, inrush current, and harmonics increase when using
multiple devices.

Parallel Use to Increase
Output Power
Devices can be paralleled to increase the output power. To parallel the devices
to increase power, you must do one of the following:
•
•
Set the output voltage of all devices to the same value (±100 mV) in
“Single Use” mode with the same load conditions on all devices.
Leave the devices with the factory settings.
After the devices are set, set each device to Parallel Use mode, in order to
achieve load sharing. The Parallel Use mode regulates the output voltage in
such a manner that the voltage at no load is approximately 4% higher than at
nominal load.
The ambient temperature is not allowed to exceed 60 °C (140 °F).
If more than three devices are connected in parallel, a fuse or circuit breaker
with a rating of 15 A or 16 A is required on each output. Alternatively, a diode or
redundancy module can also be used.
Energize all devices simultaneously. If the output was in overload or short
circuits, and the required output current is higher than the current of one unit,
it might be necessary to cycle the input power. To cycle the input power, turn
off the device and keep off for at least 5 seconds.
Keep an installation clearance of 15 mm (0.59 in.) (left / right) between two
devices and avoid installing devices on top of each other. Do not use devices in
parallel in the following conditions:
•
•
The device is mounted in an orientation other than the standard
mounting orientation.
Any condition where a reduction of the output current is required, such
as altitude.
Leakage current, EMI, and inrush current increase when using multiple
devices.

Parallel Use for Redundancy This section includes 1+1 Redundancy and N+1 Redundancy.
1+1 Redundancy
Devices can be paralleled for 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.
Decoupling helps ensure that the output voltage is maintained. Decoupling
accomplishes this by preventing a defective device from becoming a load for
the other device.
1+1 redundancy allows ambient temperatures up to 70 °C (158 °F).
Leakage current, EMI, inrush current, and harmonics increase when using
multiple devices.
Recommendations for building redundant power systems:
•
•
•
•
•
28
Use separate input fuses for each device.
Use separate mains systems for each device whenever it is possible.
Monitor the individual devices. Therefore, use the DC OK signal of the
device.
It is desirable to set the output voltages of all devices to the same value (±
100 mV) or leave it at the factory setting.
Set the devices into “Parallel Use” mode.
Rockwell Automation Publication 1606-RM103A-EN-P - July 2020
N+1 Redundancy
Redundant systems for a higher power demand are usually built in a N+1
method. For example, four devices, each rated for 10 A, are paralleled to build a
30 A redundant system.
Leakage current, EMI, inrush current, and harmonics increase when using
multiple devices.
Keep an installation clearance of 15 mm (0.59 in.) (left / right) between two
devices and avoid installing 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.
For N+1 redundancy the ambient temperature is not allowed to exceed
60 °C (140 °F).
See the following figures for wiring examples.

Operation On Two Phases
The power supply can be used on two-phases of a three-phase-system. Such a
phase-to-phase connection is allowed as long as the supplying voltage is below
240V+10%.
Ensure that the wire, which is connected to the N-terminal, is appropriately
fused.
The maximum allowed voltage between a Phase and the PE must be below
300V AC.

Use in a Tightly Sealed
Enclosure
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 box, no
other heat producing items are inside the box. The load is placed outside the
box.
The temperature sensor inside the box is placed in the middle of the right side
of the power supply 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.
