QT20.241, QT20.241-C1
Q-Series
24V, 20A, THREE PHASE INPUT
Apr. 2017 / Rev. 2.1 DS-QT20.241-EN
16. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection typ. 32Vdc
max. 35Vdc
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 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 Not included
*) 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 62477-1, IEC 62103, IEC 60364-4-41
Class of protection I PE (Protective Earth) connection required
Isolation resistance > 500MOhm Input to output, 500Vdc
PE resistance < 0.1Ohm
Touch current (leakage current) typ. 0.44mA / 0.94mA At 3x400Vac, 50Hz, TN-,TT-mains / IT-mains
typ. 0.62mA / 1.31mA At 3x480Vac, 60Hz, TN-,TT-mains / IT-mains
max. 0.54mA / 1.12mA At 3x440Vac, 50Hz, TN-,TT-mains / IT-mains
max. 0.78mA / 1.62mA At 3x528Vac, 60Hz, TN-,TT-mains / IT-mains
*) double or reinforced insulation
15/27
All parameters are typical values specified at 24V, 20A, 3x 400Vac, 50Hz, symmetrical mains voltages, 25°C ambient and after
a 5 minutes run-in time unless otherwise noted.
