16. PROTECTION FEATURES
Buffer protection Electronically protected against overload, no-load and short-circuits
Output over-voltage protection
in buffer mode
typ. 32Vdc
max. 35Vdc
In case of an internal defect, a redundant circuitry
limits the maximum output voltage. The output shuts-
down and makes restart attempts automatically.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm e.g. screws, small parts
Reverse polarity protection yes max. –35Vdc
Input over-voltages protection yes max. 35Vdc, no harm or defect of the unit
Internal fuse not included
17. SAFETY
