Offers hot plug-in operation
Isolated input and output
Optional extended temperature range
Optional supervisory control module

The CSM02 is a compact, modular DC-DC converter system designed for communications applications. The CSM02 DC-DC converter utilizes Argus’ advanced switched-mode technology to provide outstanding efficiency in a compact design. Available in either a horizontal or vertical cabinet configuration, the CSM02 achieves power conversion efficiencies greater than 85 percent at full load, resulting in significant energy savings over competitive units.

The CSM02 incorporates a comprehensive range of standard and optional features allowing it to fulfill an extensive list of applications. Standard features include input/output termination’s, current limit, over voltage protection, test points, over temperature protection and fuses. Options include low temperature operation, low/high voltage alarm, adjustable OVP, fuse distribution, input breaker, on board microprocessor for remote monitoring, and a serial communications interface.
