Protective functions and safety features

Protective functions

Output protection

Electronically protected against overload, no load and short circuit.
Audible noises may occur in the event of a protection event.

Output overvoltage protection

Typ. 30.5Vdc
Max. 32Vdc

In the event of an internal power supply fault, a redundant circuit limits the maximum output voltage. The output switches off and automatically tries to switch on again.

Protection class

IP 20

According to EN/IEC 60529
Caution: For use in a controlled environment in accordance with CSA 22.2 No. 107.1-01.

Overtemperature protection

yes

Output shutdown with automatic restart.

Protection against input transients

MOV (metal oxide varistor)

For further information see EMC chapter

Input fuse

yes

Fuse cannot be replaced by the user.

Safety features

Input/output isolation

SELV

IEC/EN 60950-1

PELV
double or reinforced insulation
