RSDB450G, RSDB550G,RSDB650G, and RSDB750G Power Supplies

RSDB750G -1 RSDB750G -2 RSDB750G -3

The RSDB450G, RSDB550G,RSDB650G, and RSDB750G 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.
