10.1
Input Fuse
A fuse mounted inside the converter protects the module
against severe defects. If operated from a DC source this
fuse may not fully protect the module when the input volt-
age exceeds 200 V DC! In applications where the convert-
ers operate at source voltages above 200 V DC an external
fuse or a circuit breaker at system level should be installed!

4 A, 250 V
1 Fuse size 5
× 20 mm
AC frequency range 47...440 Hz.
Above 70 Hz (at
Ui = 264 V AC) the earth lekage current may exceed 3.5 mA, specified in IEC 950. The built-in Y capacitors
are specified for
≤100 Hz. Above 350 Hz the input voltage may not exceed 200 V AC.
Input Under-/Overvoltage Cut-out
If the input voltage remains below approx. 0.8
Ui min or ex-
ceeds approx. 1.1
Ui max, an internally generated inhibit sig-
nal disables the output(s). When checking this function the
absolute maximum input voltage rating
U i abs should be
considered!
Input Transient Protection
A suppressor diode or a VDR (depending upon the input
voltage range) together with the input fuse and a symmetri-
cal input filter form an effective protection against high input
transient voltages.
Reverse Polarity Protection
The built-in rectifier provides reverse polarity protection at
the input.
Inrush Current Limitation
The modules of the versions -7, -6, -5 incorporate a NTC re-
sistor in the input circuitry which - at initial turn on - reduces
the peak inrush current value by a factor of 5...10 to protect
connectors and switching devices from damage. Subse-
quent switch-on cycles within short periods will cause an
increase of the peak inrush current value due to the warm-
ing-up of the NTC resistor. (see also option E)
Inrush Current Peak Value
The inrush current peak value/initial switch-on cycle) can
be determined by following calculation: (See also Input In-
rush Current Characteristic).
