SFP650-12BG

SFP650-12BG AC-DC Front-End Data Sheet 12V Output, 650 Watts Features  Ideal server form factor optimizes, space, efficiency, and load variations  High efficiency maximized between 30-80% load conditions  Unconditionally stable under any load condition  Wide range DC-input model available (SFD550-12BG)  Wide input voltage range (90-264 VAC) with PFC  1U or 2U height configurations  Active current share with ORing FET  I2C interface status monitoring  Standby voltage of 3.3 VDC @ 3 A  Overtemperature, overload, and overvoltage protection  Status LEDs: AC OK, POWER GOOD, PS FAIL Applications  Datacom  Distributed power systems Description The SFP650-12BG is a 650-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 I2C management interface bus. The SFP650-12BG meets international safety requirements and is CE marked to the Low Voltage Directive (LVD).
