1 With double output modules, both outputs loaded with Io nom.
2 Valid for -7 versions with NTC, (-9 versions exclude the NTC). Initial switch-on cycle. Subsequent switch-on/off cycles increase the
inrush current peak value.
3 AS, BS and FS types have no NTC (inrush current limiter) fitted.
4 1 s max., duty cycle 1% max.
Input Under-/Overvoltage Lock-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
Ui abs should be
considered! Between
Ui min and the undervoltage lock-out
level the output voltage may be below the value defined in
table:
Output data (see: Technical Information: Measuring
and Testing).
Inrush Current Limitation
The CS, DS, ES modules incorporate an 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. 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:
E option.
