Protective functions and safety features
Protective functions | ||
---|---|---|
Output protection | Electronically protected against overload, no load and short circuit. | |
Output overvoltage protection | Typ. 31Vdc | 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 remains switched off until the input voltage is switched off for at least one minute and then switched on again, or until the green LED has gone out. |
Protection class | IP 20 | According to EN/IEC 60529 |
Overtemperature protection | - |
|
Protection against input transients | MOV (metal oxide varistor) |
|
Input fuse | yes | Slow-blow fuse cannot be replaced by the user. |
