QS20.241, QS20.241-A1, QS20.241-C1
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 > 3.5mm / > 5mm top side / bottom side; 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.
17. SAFETY FEATURES
Input / output separation
*) SELV IEC/EN 60950-1
PELV IEC/EN 60204-1, EN 50178, IEC 62103, IEC 60364-4-41
double or reinforced insulation
Class of protection I PE (Protective Earth) connection required
Isolation resistance > 5MOhm input to output, 500Vdc
PE resistance < 0.1Ohm
Touch current (leakage current) typ. 0.23mA / 0.63mA 100Vac, 50Hz, TN-,TT-mains / IT-mains
typ. 0.34mA / 0.93mA 120Vac, 60Hz, TN-,TT-mains / IT-mains
typ. 0.58mA / 1.56mA 230Vac, 50Hz, TN-,TT-mains / IT-mains
< 0.31mA / 0.77mA 110Vac, 50Hz, TN-,TT-mains / IT-mains
< 0.45mA / 1.13mA 132Vac, 60Hz, TN-,TT-mains / IT-mains
< 0.80mA / 2.00mA 264Vac, 50Hz, TN-,TT-mains / IT-mains
