15. Protection Features
Output protection
Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection
typ. 31Vdc
max. 32.5Vdc
In case of an internal power supply fault, a redundant
circuit limits the maximum output voltage. In such a
case, the output shuts down and stays down until the
input voltage is turned off and on again.
Output over-current protection
electronically limited
see Fig. 5-1
Degree of protection
IP 20
EN/IEC 60529
Penetration protection
> 2.5mm in diameter
e.g. screws, small parts
Over-temperature protection
Not included
Input transient protection
