Protection features
| Output protection | Electronically protected against overload, no-load and short-circuits*) | |
| Output overvoltage protection | typ. 30Vdc | in case of an internal power supply defect, a redundant circuit limits the maximum output voltage. The output shuts down and automatically attempts to restart. | 
| Degree of protection | IP 20 | EN/IEC 60529 | 
| Penetration protection | > 5mm | e.g., screws, small parts | 
| Over-temperature protection | yes | Output shut-down with automatic restart | 
| Input transient protection | MOV (Metal Oxide Varistor) | 
 | 
| Internal input fuse | Included | not user replaceable | 
*) In case of a protection event, audible noise may occur.
