Protective functions and safety features
Protective functions | ||
---|---|---|
Output overvoltage protection | Typ. 30.5 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. |
Protection against | MOV (metal oxide varistor) | For further information see EMC chapter |
Input fuse | Included | Slow-blow fuse, not user-replaceable, with high braking power |
Safety features | ||
---|---|---|
Insulation resistance | Min. 500 MOhm | In the delivery state between input and output, |
Min. 500 MOhm | In the delivery state between input and PE (Protective Earth), | |
Min. 500 MOhm | In the delivery state between output and PE, | |
Min. 500 MOhm | In the delivery state between output and DC-OK contacts, | |
Protection class | I | According to IEC 61140 |
Touch current (leakage current) | Typ. 0.33 mA / 0.69 mA | At 230 Vac, 50 Hz, TN, TT / IT network |
Max. 0.43 mA / 0.89 mA | At 264 Vac, 50 Hz, TN, TT / IT network |
