The CSM01 is a compact, modular DC to DC converter system designed for communications applications. Using switched-mode technology, the CSM01 provides outstanding efficiency in a compact design. The CSM01 achieves power conversion efficiencies greater than 85 percent at full load, resulting in significant energy saving over competitive units. The CSM01 packs maximum power into minimum space, but doesn’t compromise on features. A fully equipped vertical mount CSM01 system can accommodate up to six modules — a total output capacity of 30A — as well as a supervisory module, distribution module and input module. Horizontal mount provides up to 15A capacity. Argus’ CSM modular DC to DC converter systems incorporate a full range of standard and optional features to meet the needs of a range of applications.
