Output protection 
Electronically protected against overload, no-load and short-circuits 
*)
 
Output over-voltage protection typ. 
31Vdc 
max. 32Vdc 
in case of an internal power supply defect, a redundant 
circuit limits the maximum output voltage. The output 
shuts down and automatically attempts to restart. 
Reverse input polarity protection  Included 
unit does not start when input voltage is reversed 
Output over-current protection electronically 
limited 
*)
 
Degree of protection 
IP 20 
EN/IEC 60529 
Penetration protection 
> 3.5mm 
e.g. screws, small parts 
Over-temperature protection 
yes 
output shut-down with automatic restart 
Input transient protection

Internal input fuse 
T15A H.B.C. 
not user replaceable 
*)   In case of a protection event, audible noise may occur.
