SFD1200-12BG Front-End Preliminary Data Sheet DC Input, 12V Output, 1200 Watts Features * * * * * * * RoHS compliant for all six substances Wide DC input range (-40 to -75 VDC) 1U or 2U height configurations Active current share with ORing FET on +12V I2C interface status and control Standby voltage of 3.3 VDC @ 3 A Overtemperature, overload, and overvoltage protection * Variable-speed fan for low noise at low ambient temperatures * Status LEDs: INPUT OK, OUTPUT OK, and FAULT Applications * Datacom * Distributed power systems * Servers Description The SFD1200-12BG is a 1200-watt, DC-input front-end which has a main 12 VDC output for datacom, distributed power, and server applications, and provides a 3.3 VDC standby output. 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, redundant configurations. Status is provided with front panel LEDs, logic signals, and via an I2C management interface bus. In addition, the I2C bus can supply status information about the power supply including output current and voltage. The SFD1200-12G meets international safety requirements for ITE and is CE marked to the Low Voltage Directive (LVD).
