Power-One launches SFP450 AC-DC front-end
Power-One has 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. 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 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 900 watts 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
