Q-Series
24V, 20A, SINGLE PHASE INPUT
16. PROTECTION FEATURES
Output protection
Electronically protected against overload, no-load and short-circuits *)
Output over-voltage protection
typ. 32Vdc
max. 37Vdc
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
Over-temperature protection
Input transient protection
