Front end power supply features I2C control

50W hot-swap AC/DC front-end uses advanced topologies and thermal management techniques to deliver 12V DC at 36.6A, with efficiencies exceeding 89%.New from Power-One is the SFP450-12BG, a 450W hot-swap AC/DC front-end. This I2C-compatible power supply uses advanced topologies and thermal management techniques to deliver 12V DC at 36.6A, with efficiencies exceeding 89% and a power density of 9W/in3. Power-One will be displaying this highly efficient product at Electronica 2006 in Munich.

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 include 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 90-264V AC input range, a 3.3V at 3A standby output, and the capability to provide 900W through parallel operation.

Ultracompact 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 US $300 each in quantities of 100.

Evaluation models are usually available from stock.

Production quantities are typically available in six to eight weeks.
