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 I 2 C management interface bus. In addition, the
I 2 C 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).
