16. P ROTECTION F EATURES
Output protection Electronically protected against overload, no-load and short-circuits
Output over-voltage protection typ. 56Vdc
max. 60Vdc In case of an internal power supply defect, a redundant
circuitry limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Output over-current protection electronically limited see Fig. 8-1
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 MOV Metal Oxide Varistor
Internal input fuse T6.3A H.B.C. not user replaceable
Note: In case of a protection event, audible noise may occur.
