BEL POWER SOLUTIONS INC Power Supply, FNP850-12RG, 12V dc, 73 A, 500 mA, 856W, Dual Output, 90 → 264V ac Input

The Power-One FNP range power supplies are power-factor-corrected (PFC) which provide either a 12 VDC or 48 VDC output, and can be used in hot-swap redundant systems. The FNP front-ends have a front-mounted AC receptacle.
The highly efficient thermal design with internal-fan cooling permits their use over wide temperature ranges and provides very high reliability. Front panel LEDs, logic signals and an I2C management interface provide status information. In addition, the I2C bus can enable the power supply, set high fan speed, adjust the output voltage, and set the output current limit.
