3.14 Protective functions and safety features
Protective functions
Output overvoltage protection Typ. 31.5 Vdc
Max. 34 Vdc In the event of an internal power supply fault, a redundant circuit limits
the maximum output voltage. In such a case the output switches off
and automatically attempts to restart.
Protection class IP20 EN/IEC 60529
Overtemperature protection Yes Output shutdown with automatic restart.
Temperature sensors are installed on critical components inside the
device and switch off the device in safety-critical situations. This can
happen, for example, if the ambient temperature is too high, ventila-
tion is obstructed or derating requirements are not met. There is no
correlation between the operating temperature and the switch-off tem-
perature, as this depends on the input voltage, the load and the instal-
lation methods.
Protection against
input transients MOV (metal oxide varis-
tor)
