Protective functions and safety features

Protective functions

Output overvoltage protection

Typ. 31 Vdc
Max. 34 Vdc

In the event of an internal power supply fault, a redundant circuit limits the maximum output voltage. The output switches off in such a case. To attempt to restart, turn off the input power for at least 90 s.

Protection class

IP20

EN/IEC 60529

Overtemperature protection

No

 

Protection against
input transients

MOV (metal oxide varistor)

For further information see EMC chapter

Input fuse

included

Slow-blow fuse, not user-replaceable, with high braking power

Safety features
