Protective functions
Protective functions | ||
|---|---|---|
Output protection | Electronically protected against overload, no load and short circuits. If the electronic output fuse is activated, an audible noise may occur. | |
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 | EN/IEC 60529 |
Ingress protection | > 4mm | e.g. screws, small parts |
Overtemperature protection | Yes | Output shutdown with automatic restart. The temperature sensor is installed at critical components within the device and switches off the device in safety-critical situations (e.g. load reduction requirements not met, excessive ambient temperature, ventilation blocked or load reduction not observed if the mounting direction is different). There is no correlation between the operating temperature and the switch-off temperature, since the latter depends on the input voltage, the load and the installation type. |
Protection against input transients | MOV (metal oxide varistor) | For further information see EMC chapter |
Input fuse | Included | Non-replaceable slow-blow fuse with high load capacity |
