16. Protection Features

Buer protection Electronically protected against overload, no-load and short-circuits

Output over-voltage protection

in buer mode

typ. 58Vdc

max. 60Vdc

In case of an internal defect, a redundant circuitry

limits the maximum output voltage. The output shuts

down and makes automatic restart attempts.

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 to the unit

Internal fuse not included

17. Safety

Output voltage SELV IEC/EN 60950-1

PELV EN 60204-1, EN 50178, IEC 60364-4-41

Class of protection II

Isolation resistance > 5MOhm Power port to housing, 500Vdc

PE resistance < 0.1Ohm between housing and chassis ground terminal

Dielectric strength 500Vac Power port to signal port

500Vac Power port / signal port to housing
