GENERAL FEATURES Hot Swappable Modules These shelf-mounted modules are easy and safe to install or remove while system is operational without affecting the overall system’s performance. Parallel Operation and Automatic Load Sharing Forced or passive load sharing is available between modules of the same operating voltages in parallel applications. Current Limit The Current Limit is adjustable between 0A to 50A. Upon exceeding this limit, the rectifier automatically reduces output voltage. Safety UL/CUL Recognized: UL 1950/CSA 950.
