SFP650 Series Converter

650-watt, power factor corrected (PFC) front-end converter from Bel Power Solutions

Bel Power Solutions SFP650-12BG is a 650-watt, power factor corrected (PFC) front-end that provides a 12VDC 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 O-ring diodes facilitate use in hot-swap (plug) 1, redundant configurations. Status is provided with front panel LEDs, logic signals, and via the I²C management interface bus. The SFP650-12BG meets international safety requirements and is CE marked to the low voltage directive (LVD). SFP650 Series Converter
