Efficient 450 W hot-swap front-end has extensive I²C interface capabilities

21 February 2007 Power Electronics / Power Management

The SFP450-12BG from Power-One is a 450 W, hot-swap, AC-DC front-end. This I²C-compatible power supply uses advanced topologies and thermal management techniques to deliver 12 V d.c. at 36,6 A, with efficiencies exceeding 89% and a power density of 0,55 W/cm³, says Power-One.

The I²C interface offers an extensive range of monitoring and control capabilities. Static information includes serial number, part number, and place/date of manufacture. Realtime data includes AC input, output voltage and current levels, fan speed, and over-temperature alarms. Remotely-controllable performance attributes include unit enable, output voltage value, and fan speed.

Additional performance features include operation over a wide 90-264 V a.c. input range, a 3,3 V @ 3 A standby output, and the capability to provide 900 W through parallel operation. It is compact (314,5 x 78 x 40 mm) for low profile 1U and 2U rack configurations. Protections include: output overvoltage, output overcurrent, and overtemperature.

The SFP450-12BG RoHS compliant and is CE marked for the European Low Voltage Directive.
