Product Overview
Figure 1 - Input Voltage Range
The 1606-XLE120F is a cost optimized power
supply that does not compromise on quality,
reliability, or performance. It covers a DC input
range up to 150V DC.
The power supply has a small size, high efficiency,
electronic inrush current limitation, active power
factor correction, and a wide operational
temperature range. The power supply has a power
reserve of 20% included, which can even be used
continuously at temperatures up to 45 °C (113 °F).
It can deliver three times the nominal output
current for 12 ms, which helps to trip fuses on
faulty output branches.
This power supply can be used in a wide variety of applications due to its high
immunity to transients and power surges, low electromagnetic emission, DC
OK signal contact for remote monitoring, and large international approval
package.

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 large capacitors, such as EDLCs (electric double layer
capacitors or “UltraCaps”) with a capacitance > 0.1 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 shortcircuits. If there is a protection event, audible noise may occur.

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, the power supply delivers continuous output current for 1 s. After this, the output is switched off for approx 9 s before a new start attempt
is automatically performed. This cycle is repeated as long as the overload exists. If the overload is cleared, the device operates normally. See Figure 11.

Lifetime Expectancy
The Lifetime expectancy values that are shown in the table indicate the
minimum operating hours (service life) and are determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is
specified in operational hours and is calculated according to the specification
of the capacitor manufacturer. 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. It is the 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.

Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
Either a double or reinforced insulation insulates the output to the input.
The manufacturer conducts type and routine tests. 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.
We recommend that either the + pole or the – pole 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.

1606-XLSRED Redundancy Module
The 1606-XLSRED is a dual redundancy module, which can be used to build 1+1
or N+1 redundant systems.
The device is equipped with two 10 A nominal input channels, which are
individually decoupled by using diode technology. The output can be loaded
with a nominal 20 A continuous current.
The device does not require an additional auxiliary voltage and is self-powered
even if there is a short circuit across the output.
For a safe and vibration resistant wiring, the device is equipped with quickconnect-spring-clamp terminals.
The unit is narrow and only requires 32 mm (1.26 in.) width on the DIN rail.
See Parallel Use for Redundancy on page 25 for wiring information.
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.

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. The same situation
applies when starting a capacitive load.
The peak current capability also helps ensure 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 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:
•
•
•
•
•
•
Use only matched batteries when putting 12V types in series.
Ensure that the ambient temperature of the power supply stays below
40 °C (104 °F).
Use a 6 A circuit breaker or a blocking diode between the power supply
and the battery.
Ensure that the output current of the power supply is below the allowed
charging current of the battery.
The return current to the power supply is typically 12 mA. This return
current can discharge the battery when the power supply is switched off
except if a blocking diode is used.
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. Set the voltage as
follows based on ambient temperature:
- 55.6V at 10 °C (50 °F)
- 55.0V at 20 °C (68 °F)
- 54.3V at 30 °C (86 °F)
- 53.6V at 40 °C (104 °F)

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.
Output
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.

Output
Devises can be paralleled to
increase the output power. Either
adjust the output voltage to the
same value (±100 mV) with the
same load conditions on all devices,
or leave the devices 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 6 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 (turn 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 power
supplies in parallel in any condition where a derating of the output current is
required, for example:
•
•
in mounting orientations other than the standard mounting orientation
(terminals on bottom of the unit)
altitude
Leakage current, EMI, and inrush current increase when using multiple
devices.

Parallel Use for Redundancy
The power supply can be used for 1+1 redundancy or N+1 redundancy. The
redundancy module that is used in this section is the 1606-XLSRED. See
1606-XLSRED Redundancy Module on page 21.
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 prevents the defective unit from becoming a load for the other device, and
thereby helps to ensure that the output voltage is maintained.
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:
•
•
•
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 either set the output voltages of all devices to the same
value (± 100 mV) or leave them at the factory setting.

N+1 Redundancy
Redundant systems for a higher power demand are usually built in an N+1
method. For example, four devices, each rated for 2.5 A, are paralleled to build a
7.5 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 40 °C
(104 °F).

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, 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.).
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure.

Mounting Orientations
Mounting orientations other than Mounting Orientation A (standard
orientation with 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 lifetime expectancy and MTBF values in
this document apply only for the standard mounting orientation.
The following curves give an indication for allowed output currents for
altitudes up to 2000 m (6560 ft).
