CSM11

Modular DC to DC Converter Part Number: 012-548-20

24 to 48VDC, 24A output 3RU high-density module Up to 3 modules per 19in or 4 modules per 23in shelves Scalable hot plug-in operation Bar graph output current indicator The CSM11 is a compact, modular DC to DC converter system designed for communications applications. Using switched mode technology, the CSM11 provides outstanding efficiency in a compact design. The CSM11 packs maximum power into minimum space, but doesn’t compromise on features. Paralleling diodes are included to optimize redundancy. A fully equipped CSM11 system will include up to three modules in a 19in shelf and up to four power modules in a 23in shelf — a total output capacity of 5000W per 23in shelf. Alpha’ CSM modular DC to DC converter systems incorporate a full range of standard and optional features.
