Protective functions and safety features
Protective functions  | ||
|---|---|---|
Output protection  | Electronically protected against overload, no load and short circuit.  | |
Output overvoltage protection  | Typ. 30.5Vdc   | 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  | IP 20  | According to EN/IEC 60529   | 
Overtemperature protection  | yes  | Output shutdown with automatic restart.  | 
Protection against input transients  | MOV (metal oxide varistor)  | For further information see EMC chapter  | 
Input fuse  | yes  | Fuse cannot be replaced by the user.  | 
Safety features  | ||
|---|---|---|
Input/output isolation  | SELV  | IEC/EN 60950-1  | 
PELV  | IEC/EN 60204-1, IEC 62477-1, IEC 60364-4-41  | |
Protection class  | I  | A PE connection (protective earth) is required.  | 
Insulation resistance  | > 5MOhm  | Input over output, 500Vdc  | 
Touch current (leakage current)  | typ. 0.30mA / 0.79mA  | At 100Vac, 50Hz, TN, TT / IT network  | 
typ. 0.42mA / 1.1mA  | At 120Vac, 60Hz, TN, TT / IT network  | |
typ. 0.67mA / 1.7mA  | At 230Vac, 50Hz, TN, TT / IT network  | |
max. 0.37mA / 0.94mA  | At 110Vac, 50Hz, TN, TT / IT network  | |
max. 0.54mA / 1.33mA  | At 132Vac, 60Hz, TN, TT / IT network  | |
max. 0.88mA / 2.18mA  | At 264Vac, 50Hz, TN, TT / IT network  | |
