Bel Power Solutions SFP450 Series is a 450 Watt, power factor

corrected (PFC) front-end which provides a 12 VDC output for datacom

and other distributed power applications. Its compact size enables

mounting in both 1U and 2U height racks. High efficiencies, advanced

thermal management techniques, and an internal fan increase reliability

over a broad range of operating conditions. Internal ORing diodes

facilitate use in hot-swap (plug)*, redundant configurations.

Status is provided with front panel LEDs, logic signals and via the I2C

management interface bus.

The SFP450 Series meets international safety requirements and is CE

marked to the Low Voltage Directive (LVD).

* Proper hot-swap (plug) operation instruction: Power supply is not intended to be inserted into

the system with AC cord already applied. Alternatively, if there is an application where power

supply insertion with AC cord is required; PS_ON must be toggled or AC recycled after

insertion into the system to reset the power supply.
