Electrical Input Data
General Conditions:
Table 3: Electrical input data
Input Fuse and Protection
A VDR together with the input fuse and a symmetrical input
filter form an effective protection against high input
transient voltages.
A fuse mounted inside the converter in series to the phase
line protects against severe defects. A second fuse in the
neutral line may be necessary in certain applications; see
Installation Instructions.
Table 4: Fuse specification
Input Under- /Overvoltage Lockout
If the input voltage remains below approx. 65 VAC (LKP:
150 VAC) or exceeds V
signal disables the output(s). Do not check the overvoltage
lockout function!
If V
level, the output voltage may be below the value specified
in the tables Electrical Output Data.

Valid for models without option E. This is the value of the NTC resistance at 25 °C and applies to cold converters for the initial
switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value.
Operation with DC input voltage is not specified and not recommended.

Inrush Current Limitation
The models without option E incorporate an NTC resistor
in the input circuitry, which at initial turn-on reduces the
peak inrush current value by a factor of 5 to 10 to protect
connectors and switching devices against 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.
The inrush current peak value (initial switch-on cycle) can
be determined by following calculation:
