PE resistance
Max. 0.1Ohm
Resistance between PE terminal and the housing in
the area of the DIN rail mounting bracket.
Output over
-voltage protection Typ. 30.5Vdc
Max. 32Vdc
In case of an internal defect, a redundant circuit limits the maximum
output voltage. The output shuts down and automatically attempts to
restart.
Class of protection
I According to IEC 61140
A PE (Protective Earth) connection is required
Degree of protection
IP 20 According to EN/IEC 60529
Ove
r-temperature protection Included
Output shuts down with automatic restart.
Temperature sensors are installed on critical
components inside the unit and turn the unit off in
safety critical situations, which can happen e.g.
when ambient temperature is too high, ventilation
is obstructed or the derating requirements are not
followed. There is no correlation between the
operating temperature and turn-off temperature
since this is dependent on input voltage, load and
installation methods.
