Protective functions and safety features

Insulation resistance

Min. 500MOhm

In the delivery state between input and output, measured with 500Vdc

Min. 500MOhm

In the delivery state between input and PE, measured with 500Vdc

Min. 500MOhm

In the delivery state between output and PE, measured with 500Vdc

Min. 500MOhm

In the delivery state between output and DC OK contacts, measured with 500Vdc

PE resistance

Max. 0.1 ohm

Resistance between PE terminal and housing in the area of the DIN rail mounting bracket.

Output overvoltage protection

Typ. 30.5Vdc
Max. 32Vdc

In the event of an internal power supply fault, a redundant circuit limits the maximum output voltage. The output switches off and automatically tries to switch on again.

Protection class

I

According to EN/IEC 61140
A PE connection (protective earth) is required.

Protection class

IP 20

According to 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, ventilation is obstructed or derating requirements are not met. There is no correlation between the operating temperature and the switch-off temperature, as this depends on the input voltage, the load and the installation methods.

Protection against input transients

MOV (metal oxide varistor)

Input fuse

included

Non-replaceable slow-blow fuse with high load capacity
