Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
Product Overview
The 1606-XLE units are high-end power supplies in a medium price range
without compromising quality, reliability, and performance. The XLE Series is
part of the Bulletin 1606 power supply family.
The 1606-XLE120E power supplies come with three connection terminal
options: screw, spring-clamp, or push-in terminals, which are optimized for
automated wiring.
The 1606-XLE120EC is equipped with conformal coated printed circuit boards
that are preferred for the use in harsh environments and the 1606-XLE120ED
features an enhanced DC input voltage range.
These units feature a small size, high efficiency, electronic inrush current
limitation, active power factor correction, and a wide operational temperature
range. The devices have a power reserve of 20% included, which can even be
used continuously at temperatures up to +45 °C (113 °F). Additionally, they can
deliver three times the nominal output current for 12 ms that helps to trip fuses
on faulty output branches.
High immunity to transients and power surges and low electromagnetic
emission, a DC OK signal contact for remote monitoring, and a large
international approval package for various applications.

Definition
PE is the abbreviation for Protective Earth and has the same meaning as the symbol.
This document uses the term ‘earth’ which is the same as the U.S. term ‘ground.’
A figure that is displayed with the AC or DC before the value represents a nominal voltage
with standard tolerances (usually ±15%) included. For example: DC 12V describes a 12V
battery disregarding whether it is full (13.7V) or flat (10V).
A figure with the unit (V AC) at the end is a momentary figure without any additional
tolerances included.
As long as not otherwise stated, AC 230V parameters are valid at 50 Hz mains frequency.

Output
The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage.
The output is designed to supply any kind of loads, including capacitive and
inductive loads. If extreme large capacitors, such as EDLCs (electric double
layer capacitors or ‘Ultra Caps’) with a capacitance > 0.3 F are connected to the
output, the unit can 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.

Included inside the power supply
The unit is resistant and does not show malfunctioning when a load feeds back voltage to the
power supply. It does not matter whether the power supply is on or off. The absorbing energy
can be calculated according to the built-in large sized output capacitor.
(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 1s. After this, the output is switched off for approx. 9s 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 will operate normally. See Figure 10

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 guarantees
a maximum life of up to 15 years (131,400 hr). Any number exceeding this value
is a calculated theoretical lifetime that can be used to compare devices.

MTBF is calculated according to statistical device failures, and indicates
reliability of a device. It is the statistical representation of the likelihood of a
unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to
fail. An MTBF figure of, for example, 1,000,000 hr means that statistically one
unit will fail 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 50,000hr or
only for 100 hr.
For these types of units, the MTTF (Mean Time To Failure) value is the same
value as the MTBF value.

Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground. The
output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests can be
conducted in the field using the appropriate test equipment that applies the
voltage with a slow ramp (2 s up and 2 s down). Connect all input-terminals
together and all output poles before conducting the test. When testing, set the
cutoff current settings to the value in the table below.
We recommend that either the + pole or the – pole is to be connected 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-XLERED20 —Redundancy Module
The 1606-XLERED20 is a dual redundancy module, which can be used to build
1+1 or N+1 redundant systems. The device is equipped with two input channels,
each rated for 20 A for ambient temperatures up to 70 °C (158 °F) and are
individually decoupled by utilizing MOSFET technology. The inputs can also
be operated up to 24 A when the ambient temperature does not exceed 45 °C
(113 °F).
The output can be loaded with nominal 20 A at 70 °C (158 °F) or 24 A at 45 °C (113
°F) continuous current.
Using MOSFETSs 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 32 mm (1.26 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.

utilizing MOSFET technology. The inputs can also be operated up to 12 A when
the ambient temperature does not exceed 45 °C (113 °F).
The output can be loaded with nominal 20 A at 70 °C (158 °F) or 24 A at 45 °C (113
°F) continuous current.
Using MOSFETSs 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 32 mm (1.26 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.
The device is equipped with an automated load sharing feature, which
balances the load current between the two input channels. It also monitors the
function of the redundancy circuitry and provides a signal if the output
current is too high, which could prevent redundancy if one power supply fails.
The signal also reports too low or too high input voltages.
1606-XLSBUFFER24—Buffer Module
The 1606-XLSBUFFER24 buffer module is a supplementary device for DC 24V
power supplies. It delivers power to bridge typical mains failures or extends
the hold-up time after the AC power is turned off.

Rockwell Automation Publication 1606-RM100A-EN-P - July 2020
Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
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.
Application Notes
All parameters are typical values that are specified at 230V AC, 50 Hz input
voltage, 24V, 5 A output load, 25 °C ambient and after a 5 minutes run-in time
unless otherwise noted.
Peak Current Capability
The unit can deliver peak currents (up to several milliseconds) which are
higher than the specified short-term currents.
This helps to start loads that demand a high 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.
The peak current capability also delivers 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:

Charging Batteries
The power supply can be used to charge lead-acid or maintenance free
batteries. Two 12V SLA or VRLA batteries are needed in series connection.
Instructions for charging batteries:
a. Use only matched batteries when putting 12V types in series.
b. Ensure that the ambient temperature of the power supply stays below 40 °C
(104 °F).
c. Use a 10 A circuit breaker or a blocking diode between the power supply
and the battery.
d. Ensure that the output current of the power supply is below the allowed
charging current of the battery.
e. The return current to the power supply is typically 8 mA. This return
current can discharge the battery when the power supply is switched off
except in case a blocking diode is utilized.
f. Set the output voltage, which is measured at no load and at the battery endof-charge voltage. The voltage should be set to the following at these
ambient temperatures:
•
•
•
•
27.8V at 10 °C (50 °F)
27.5V at 20 °C (68 °F)
27.15V at 30 °C (86 °F)
26.8V at 40 °C (104 °F)
Series Operation
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
Output 60V DC must be installed with a protection against touching.
Avoid return voltage (load, and 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 will increase when using
multiple devices.
Parallel Use to Increase Output Power
Devices can be paralleled to increase the output power. The output voltage
shall be adjusted to the same value (±100 mV) with the same load conditions on
all devices, or the devices can be left with the factory settings. The ambient
temperature is not allowed to exceed 40 °C (104 °F).
If more than three devices are connected in parallel, a fuse or circuit breaker
with a rating of 10 A is required on each output. Alternatively, a diode or
redundancy module can also be utilized.
Energize all devices simultaneously. It can be necessary to cycle the input
power (turn-off for at least 5 seconds), if the output was in overload or short
circuits and the required output current is higher than the current of one unit.
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 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).
Pay attention that leakage current, EMI, inrush current will increase when
using multiple devices.

Parallel Use for Redundancy
Please note that there are variants with built-in redundancy available in the
XLE Series. Check XLE Series -Rx units.
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.
This helps prevent the defective unit from becoming a load for the other
device, which helps to ensure that the output voltage can be maintained.
1+1 redundancy allows ambient temperatures up to 70 °C (158 °F).
Pay attention that leakage current, EMI, inrush current, harmonics will
increase when using multiple devices. Recommendations for building
redundant power systems:
•
•
•
•
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.
N+1 Redundancy:
Redundant systems for a higher power demand are built in a N+1 method. For
example four devices, each rated for 5 A, are paralleled to build a 15 A
redundant system.
Pay attention that leakage current, EMI, inrush current, harmonics will
increase when using multiple devices.
Keep an installation clearance of 15 mm (0.6 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
40 °C (104 °F).

Operation on Two Phases
The power supply can also 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 the wire, which is connected to the N-terminal, is appropriately fused.
Maximum allowed voltage between a phase and PE must be below 300V AC.

Use in a Tightly Sealed Enclosure
When the power supply is installed in a tightly sealed enclosure, the
temperature inside the enclosure will be higher than outside. In such
situations, the inside temperature defines the ambient temperature for the
power supply.
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure. The power supply is placed in the
middle of the box, no other heat producing items are inside 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 10 mm (0.39 in.).
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure.
