FSAK1200F -1 FSAK1200F -2 FSAK1200F -3

The FSAK1200F power supply is 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 AC input is rated 90-264Vrms with power factor corrected (PFC > 0.95). A 38mm high reliable Sanyo Denki fan is installed to the power supply module for cooling the power supply module.

The series of power supply also design with the output power range from 750W to 1200W and with +12V & +5Vsb output rails for 1U/2U system application.

Option: Power cord retention kit is available for this power module.
