Input Inrush Current An NTC limits the input inrush current after turn-on of the input voltage. The
inrush current is dependent on input voltage and ambient temperature. The
output load has no impact on the inrush current value.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.

Output The output provides a SELV/PELV/ES1 rated voltage, which is galvanically
isolated from the input voltage.
The output is electronically protected against no-load, overload, and short
circuit. If there is a protection event, audible noise may occur.
The output is designed to supply any kind of loads, including inductive and
capacitive loads. Capacitive loads should not be larger than 2500 μF with 2.5 A
or 5000 μF with 1.25 A additional current load.
At heavy overloads (when output voltage falls below 14V), the power supply
delivers continuous output current for 25 ms. After this, the output is switched
off for approximately 145 ms 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.

Hold-up Time The hold-up time is the time during which the 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 status indicator is also on during this time.

Connection Terminals The terminals are IP20 fingersafe constructed and are suitable for field wiring
and factory wiring.
Lifetime Expectancy The lifetime expectancies that are shown in the table indicate the minimum
operating hours (service life). The lifetime expectancy of the built-in
electrolytic capacitors determines the lifetime expectancy of the power supply.
Lifetime expectancy is specified in operational hours and is calculated
according to the 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 that exceeds 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 as
the MTBF value.
Electromagnetic

Safety and Protection
Features
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 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 phase-terminals
together and all output poles before conducting the test. When testing, set the
cutoff current settings to the value in the following table.
It is recommended 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.

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
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.
Leakage current, EMI, inrush current, and harmonics increase when using
multiple devices.
Figure 24 - Series Operation
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 that the wire, which is connected to the N-terminal, is appropriately
fused.
