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 capacitors with a capacitance > 3 F are connected to the
output, the unit might charge the capacitor in an intermittent mode. Example
capacitors with a capacitance > 3 F may include electric double layer capacitors
(EDLCs or UltraCaps).
The output is electronically protected against overload, no-load, and short-
circuits. If there is a protection event, audible noise may occur.
(1) At heavy overloads (when output voltage falls below 13V), the power supply delivers
continuous output current for 2…5 s. After this, the output is switched off for approximately
7 s before a new start attempt with duration of 1 s is automatically performed. This cycle is
repeated as long as the overload exists. If the overload has been cleared, the device operates
normally.

Hold-up Time The hold-up time is the time during which output voltage of a power supply
remains within specification following the loss of input power. The hold-up
time is output load dependent. At no load, the hold-up time can be up to
several seconds. The green DC OK lamp is also on during this time.

Connection Terminals The terminals are IP20 fingersafe constructed and suitable for field- and
factory wiring.
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 manufacturer specification of
the capacitor. The manufacturer of the electrolytic capacitors only states a
maximum life of up to 15 years (131,400 h). Any number exceeding this value is
a calculated theoretical lifetime which can be used to compare devices.
Mean Time Between Failure 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 h 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 h or only
for 100 h.
For these types of units, the mean time to failure (MTTF) value is the same
value as the MTBF value.

inside the unit and turn off the unit in safety critical situations. Examples of such situations include
when ambient temperature is too high, ventilation is obstructed, or the derating requirements are 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.
The output is insulated to the input by a double or reinforced insulation.
The manufacturer constructs 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 table below.
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.
Figure 20 - Dielectric strength
(1) When testing input to DC OK, ensure that the maximal voltage between DC OK and the
output is not exceeded (column D). We recommend connecting DC OK pins and the output
pins together when performing the test.

Accessories This section describes accessories that can be used with the power supply.
1606-XLSRED4HE Redundancy Module
The 1606-XLSRED4HE 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 by 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 36 mm (1.42 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 26 A. This is typically achieved when the power supplies are
featured with an intermittent overload behavior (Hiccup Mode).
See Parallel Use for 1+1 Redundancy on page 22 for wiring information.
1606-XLBRED20 Redundancy Module
The 1606-XLBRED20 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.
The unit is narrow and only requires 39 mm (1.54 in.) width on the DIN rail.
See Parallel Use for 1+1 Redundancy on page 22 for wiring information.
