Description

Overview Slimline 3-phase power supply for low power ratings The SITOP PSU300E 3-phase power supply is designed with a 5 A output current for 24 V applications with low power requirements. The metal enclosure is only 42 mm wide and does not require any lateral gap to other devices on the DIN rail. This is made possible by the low heat dissipation (90% efficiency). The wide-range input from 320 V to 550 V AC permits mains buffering times of 50 ms and thus allows the supply to be used in unstable three-phase networks, thanks to UL certification also in North America. The removable plug-in terminals simplify the AC and DC connection. Efficiency - Efficiency at Vout rated, Iout rated, approx. : 90 % - Power loss at Vout rated, Iout rated, approx. : 13 W Closed-loop control - Dynamic mains compensation (Vin rated ±15 %), max. : 3 % - Dynamic load smoothing (Iout: 50/100/50 %), Uout ± typ. : 5 % - Load step setting time 50 to 100%, typ. : 1 ms - Load step setting time 100 to 50%, typ. : 1 ms - Dynamic load smoothing (Iout: 10/90/10 %), Uout ± typ. : 1 % - Load step setting time 10 to 90%, typ. : 1 ms - Load step setting time 90 to 10%, typ. : 1 ms - Setting time maximum : 30 ms Protection and monitoring - Output overvoltage protection : Yes, according to EN 60950-1 - Current limitation, typ. : 11 A - Property of the output Short-circuit proof : Yes - Short-circuit protection : Electronic shutdown, automatic restart - Enduring short circuit current RMS value : ● maximum7.5 A Safety - Primary/secondary isolation : Yes - Galvanic isolation : Safety extra-low output voltage Uout acc. to EN 60950-1 and EN 50178
