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. 31Vdc
Max. 34Vdc

In the event of an internal power supply fault, a redundant circuit limits the maximum output voltage. In such a case the output switches off and remains switched off until the input voltage is switched off for at least one minute and then switched on again, or until the green LED has gone out.

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

-

 

Protection against input transients
