Product Overview
The 1606-XLE260F power supply is part of a series of high-end power supplies
in a medium price range that do not compromise quality, reliability, or
performance. The 1606-XLE260F features high efficiency, advanced inrush
current limitation, active power factor correction (PFC), and a wide
operational temperature range.
The 1606-XLE260F includes all essential basic functions of a power supply. It
has a power reserve of 10% up to 60 °C (140 °F) and 20% up to 45 °C (113 °F)
included, even when used continuously. Additionally, the power supply can
deliver three times the nominal output current for at least 12 ms, which helps
to trip fuses on faulty output branches. The power supply has a wide variety of

Input Inrush Current
An active inrush limitation circuit (NTCs, which are bypassed by a relay
contact) limits the input inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.

Included inside the power supply
(1) Power Boost This power/ current is continuously allowed up to an ambient temperature of 45 °C (113 °F). Above 45 °C (113 °F), do not use this power/
current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
(2) HiccupPLUS Mode At heavy overloads (when output voltage falls below 26V), the power supply delivers continuous output current for 2 s. After this, the
output is switched off for approx 18 s 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 13.
(3) Discharge current of output capacitors is not included.

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’s manufacturer
specification. The manufacturer of the electrolytic capacitors only states a
maximum life of up to 15 years (131,400 hr). Any number exceeding 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. 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 value is a statistical representation of the likelihood of a device to
fail. 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.

Output shutdown with automatic restart.
The temperature sensor is installed on critical components inside the unit and
turns off the unit in safety-critical situations. For example, when derating
requirements are not observed, there is a high ambient temperature, ventilation is
obstructed, or the mounting orientation derating is not followed. There is no
correlation between the operating temperature and turn-off temperature since
this is dependent on input voltage, load, and installation methods.

Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
Type and factory tests are conducted by the manufacturer. Field tests may 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 and all output poles before conducting the test. When testing, set the
cutoff current settings to the value in the following table.
To fulfill the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the – pole, or any other part of the output
circuit shall 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.

Redundancy Modules
This section provides information about redundancy modules that can be used
with the power supply.
1606-XLSRED – 2 x 10 A Inputs, 1 x 20 A Output
The 1606-XLSRED is a dual redundancy module, which has two diodes as
decoupling devices included. It can be used for various purposes. The most
popular application is to configure highly reliable and truly redundant power
supply systems. Another application is the separation of sensitive loads from
non-sensitive loads. This avoids the distortion of the power quality for the
sensitive loads, which can cause controller failures.
The 1606-XLSRED does not require an additional auxiliary voltage and is selfpowered even if there is a short circuit across the output.
The unit is slender and only requires 32 mm (1.26 in.) width on the DIN rail.
1606-XLSRED40HF – 2 x 20 A Inputs, 1 x 40 A Output
The 1606-XLSRED40HF is equipped with two input channels, which are
individually decoupled by using MOSFET technology. Using MOSFETs instead
of diodes reduces the heat generation and the voltage drop between input and
output. The 1606-XLSRED40HF does not require an additional auxiliary
voltage and is self-powered even in case of a short circuit across the output.
Due to the low power losses, the unit is slender and only requires 46 mm
(1.81 in.) width on the DIN rail.

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
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 (including the
PowerBoost). The same situation applies when starting a capacitive load.
The peak current capability also ensures 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 two examples show typical voltage dips for resistive loads:

The unit is tested and approved for branch circuits up to 30 A (UL) and 32 A
(IEC). An external protection is only required if the supplying branch has an
ampacity greater than this. Check also local codes and local requirements. In
some countries, local regulations might apply.
If an external fuse is used, minimum requirements must be considered to
avoid nuisance tripping of the circuit breaker. A minimum value of 6 A B- or CCharacteristic breaker should be used.
Rockwell Automation Publication 1606-RM112A-EN-P - September 2020

Back-feeding Loads
Loads such as decelerating motors and inductors can feed voltage back to the
power supply. This feature is also called return voltage immunity or resistance
against back electro magnetic force (back EMF).
This power supply 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 maximum allowed feed-back-voltage is 63V DC. The maximum allowed
feed-back peak current is 21 A. Higher currents can temporarily shut down the
output voltage. The absorbing energy can be calculated according to the builtin large sized output capacitor which is specified in Output on page 11.
Output Circuit Breakers
Standard miniature circuit breakers (MCBs or UL 1077 circuit breakers) are
commonly used for AC-supply systems and may 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 thermally safe regardless of whether the MCB opens or
not.
To avoid voltage dips and undervoltage situations in adjacent 48V 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 CCharacteristic MCBs magnetically trip depending on the wire cross-sectional
area and wire length. The maximal wire length includes both the length of wire
to the load and the length back (+ and – wire lengths combined, as shown in
Figure 43).

Parallel Use to Increase
Output Power
1606-XLE260F power supplies can be paralleled to increase the output power.
The output voltage of all power supplies shall be adjusted to the same value
(±100 mV) with the same load conditions on all units, or the units can be left
with the factory settings. The power supply does not have a feature that
balances the load current between the power supplies. Usually the power
supply with the higher adjusted output voltage draws current until it goes into
current limitation. This means no harm to this power supply as long as the
ambient temperature stays below 40 °C (104 °F).
If more than three units are connected in parallel, a fuse or circuit breaker with
a rating of 10 A or 12 A is required on each output. Alternatively, a diode or
redundancy module can also be used.
Energize all units simultaneously to avoid the overload HiccupPLUS mode. If
the output was in HiccupPLUS mode due to overload or short circuits, and the
required output current is higher than the current of one unit, then you may
need to cycle the input power (turn-off for at least 5 seconds).
Restrictions: 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 parallel in any condition where a
derating of the output current is required, such as the following:
•
•
mounting orientations other than the standard mounting orientation
(terminals on bottom of the unit)
altitude
Leakage current, EMI, inrush current, and harmonics increase when using
multiple power supplies.

Parallel Use for Redundancy Power supplies 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 power supply unit fails. The simplest way is to put
two decoupled power supplies in parallel. This is called a 1+1 redundancy. In
case one power supply unit fails, the other one is automatically able to support
the load current without any interruption. Redundant systems for a higher
power demand are usually built in an N+1 method. For example five power
supplies, each rated for 5 A are paralleled to build a 20 A redundant system. For
N+1 redundancy the same restrictions apply as for increasing the output
power, see also Parallel Use to Increase Output Power on page 27.
Always use a redundancy module to decouple power supplies from each other.
This helps prevent a defective power supply from becoming a load for the other
power supplies, which helps ensure that the output voltage is maintained.
Further information and wiring configurations can be found in Redundancy
Modules on page 24.
Recommendations for building redundant power systems:
•
•
Use separate input fuses for each power supply.
Monitor the individual power supply units. Therefore, use the DC OK
relay contact of the power supply.
It is desirable to set the output voltages of all units to the same value (±
100 mV) or leave it at the factory setting.

Series Operation
Power supplies 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 are not SELV anymore and can be dangerous. Such
voltages must be installed with a protection against touching.
Earthing of the output is required when the sum of the output voltage is above
60V DC.
Avoid return voltage (for example, from a decelerating motor or battery) which
is applied to the output terminals.
Restrictions: 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 (terminals on bottom of the unit).
Leakage current, EMI, inrush current, and harmonics increase when using
multiple power supplies.

(see notes)
The unit is designed to supply any kind of loads, including capacitive and
inductive loads. If very large capacitors, such as electric double layer capacitors
(EDLCs or “UltraCaps”) with a capacitance larger than 0.5 F, are connected to
the output, the unit might charge the capacitor in the HiccupPLUS mode (see
Output on page 11).

Use In a Tightly Sealed
Enclosure
When the power supply 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 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, and 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 1 cm (0.39 in.).

Mounting Orientations
Mounting orientations other than Mounting Orientation A (Standard
Orientation) require a reduction in continuous output power or a limitation in
the maximum allowed ambient temperature. The amount of reduction
influences the lifetime expectancy of the power supply. Therefore, mounting
orientations B, C, D, and E are displayed with two different derating curves for
continuous operation:
•
•
Curve A1: Recommended output current.
Curve A2: Maximum allowed output current (results in approximately
