3-phase, 24 V DC (SITOP PSU300E)
■
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 require-
ments. The metal enclosure is only 42 mm wide and does not re-
quire 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.
