3-phase, 24 V DC Siemens

Обзор



The SITOP PSU300B 3-phase power supplies (24 V DC/17 A and 30 A) are suitable for battery charging, thanks to their constant-current characteristic. For other applications the output characteristic can also be switched to latching shutdown. The three-phase, wide-range input enables them to be used worldwide. The slim design requires little space on the DIN rail. Installation gaps are not required.
