CSM36
Modular DC to DC Converter
Part Number: 012-552-20
  • Remote equipment powering over multiple copper pairs
  • 48VDC to +/-190VDC (CSM36)
  • Two 100VA circuits per power module
  • Up to 2400W per 19in shelf
  • Scalable hot plug-in operation

The CSM36 is a compact, modular DC to DC converter system designed for distributed power communications applications, specifically optical network units. Using switched mode technology, the CSM36 provides outstanding efficiency in a compact design.

The CSM36 packs maximum power into minimum space, but doesn’t compromise on features. A fully equipped CSM36 system will include up to 12 modules in a 19in shelf.

Alpha CSM 3x modular DC to DC converter systems incorporate a full range of standard and optional features, including current/power limiting and individual ground fault interrupt options for each circuit.
