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, redundant configurations.
Status is provided with front panel LEDs, logic signals, and via the I2C management interface bus. In addition, the
I2C bus can enable the power supply and control fan speed.
The SFP450-12BG meets international safety requirements and is CE marked to the Low Voltage Directive (LVD).
