Protective functions
Protective functions
Output protection
Electronically protected against overload, no load and short circuits
1)
Output overvoltage protection
Typ. 30 Vdc
Max. 32 Vdc
In the event of an internal power supply fault, a redundant circuit
limits the maximum output voltage. The output switches off and au-
tomatically tries to switch on again.
Protection class
IP20
EN/IEC 60529
Ingress protection
> 5 mm
e.g., screws, small parts
Overtemperature protection
Yes
Output shutdown with automatic restart.
Protection against input transients
MOV (metal oxide varis-
tor)
Input fuse
included
Not user-replaceable
1)
In the event of a protection event, audible noises may occur.

between input and output, measured with 500 Vdc
PE resistance
< 0.1 ohm
Resistance between the protective conductor connection and the
housing near the DIN rail mounting bracket.
