Input Fuse
A fuse mounted inside the converter protects the module
against severe defects. This fuse may not fully protect the
module when the input voltage exceeds 200 V DC! In appli-
cations where the converters operate at source voltages
above 200 V DC an external fuse or a circuit breaker at sys-
tem level should be installed!

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 which typically occur in most installa-
tions, but especially in battery driven mobile applications.
Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72,
110 and 220 V. In most cases each nominal value is speci-
fied to a tolerance of –30 %/+25%.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 571-1. The
power supply must not switch off during these surges and
since their energy can not practically be absorbed an ex-
tremely wide input range is required.The EK input range for
110 V batteries has been designed to meet this requirement
and is available upon customer request.
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!
Inrush Current Limitation
The C/D/E/LK modules of the versions -7, -6, -5 incorpo-
rate a NTC resistor 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. Subsequent switch-on cycles within short periods
will cause an increase of the peak inrush current value due
to the warming-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)
