RRDBxGH and RSDBxG Series Power Supplies

RRDBxGH and RSDBxG Series Power Supplies


The RRDBxGH and RSDBxG series power supplies are capable of “HOT SWAP” exchanging with active current sharing and OR-ing isolation MOSFETs built in for +12V output, and droop current sharing and OR-ing isolation diode built in for +5Vsb output. The DC -48V input is rated -36VDC to -60VDC/-72VDC. A 38mm high reliable Sanyo Denki fan is installed to the power supply module for cooling the power supply module.
