Description
The SFP450-12BG 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) 1 , redundant
configurations.
Status is provided with front panel LEDs, logic signals, and via the I 2 C management interface bus.
The SFP450-12BG 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.
