November 08, 2006 by Jeff Shepard

Power-One, Inc. introduced the SFP450-12BG; a 450W, hot-swap, ac-dc front-end. This I2C-compatible power supply utilizes advanced topologies and thermal management techniques to deliver 12Vdc at 36.6A, with efficiencies exceeding 89% and a power density of 9W/in3.

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

Additional performance features include operation over a wide 90-264Vac input range, a 3.3V @ 3A standby output, and the capability to provide 900W through parallel operation. Ultra-compact 12.4 x 3.1 x 1.6 inch (314.5 x 78 x 40mm) overall dimensions facilitate low profile 1U and 2U rack configurations. Protections include: output overvoltage, output overcurrent, and overtemperature.

The SFP450-12BG is RoHS compliant for all six substances and displays the CE mark for the European Low Voltage Directive. Pricing is $300 each in quantities of 100. Evaluation models are usually available from stock. Production quantities are typically available in six to eight weeks.
