1050 W front end for distributed power systems

27 May 2009 Power Electronics / Power Management

Power-One has announced the availability of its SFP1050-12BG, a 1050 W, AC-DC front-end providing a maximum 86,7 A with a 12 V output.

The SFP1050-12BG exceeds the efficiency requirements of the Climate Savers Computing Initiative’s Silver standard across output loads of 20 to 100%. This, plus active current sharing, make it suitable for redundant applications for datacom, server and other distributed power applications.

Typically, the SFP1050-12BG with a wide-range input from 90 to 264 V a.c. has greater than 91% efficiency, even at 50% loads. A compact 1U size allows for five SFP1050’s (5250 W) to be placed in a single 1U, 19-inch rack. Blind mate connectors allow for hot swapping in live redundant systems to allow full-time power availability.

Additional features include a standby 3,3 V, 3 A output, as well as I²C monitoring and control. Protections include output over-voltage, output over-current and over-temperature. The SFP1050-12BG meets international safety requirements and is CE marked to the Low Voltage Directive (LVD).
