The Bel Power Solutions SFP1050-12BG is a 1050 W, 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 * FETs facilitate use in hot-swap (plug) , redundant configurations. Status is provided with front panel 2 LEDs, logic signals, and via the I C management interface bus. Ideal server form factor optimizes, space, efficiency, and load variations The SFP1050-12BG meets international safety High efficiency maximized between requirements and is CE marked to the Low Voltage 30-80% load conditions Directive (LVD). Unconditionally stable under any load condition Wide input voltage range (90-264 VAC) with PFC 1U or 2U height configurations * Proper hot-swap (plug) operation instruction: Power supply is not intended Active current share with ORing FET 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 Incorporate Remote sense required PS ON must be toggled or AC recycled after insertion into the 2 I C interface status monitoring system to reset the power supply.
