16. Protection Features
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection typ. 58.5Vdc
max. 60Vdc
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.
Degree of protection IP 20 EN/IEC 60529
Caution: For use in a controlled environment according
to CSA 22.2 No 107.1-01.
Penetration protection > 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 included not user replaceable
*) In case of a protection event, audible noise may occur.
17. Safety Features
