The Bel Power Solutions SFD1200-12BG is a 1200-watt, DC-input front-end power supply featuring a main 12 VDC output and a 3.3 VDC standby output. It is designed for datacom, distributed power systems, and server applications, supporting both 1U and 2U height rack configurations.
Key electrical specifications include a wide DC input range of -40 to -75 VDC, a nominal output voltage of 12 VDC, and a maximum output current of 99.2A, delivering up to 1200W of power. The unit boasts high efficiencies, reaching up to 91% under specific load conditions, and features overtemperature, overload, and overvoltage protection.
For enhanced reliability and system integration, the SFD1200-12BG incorporates internal ORing FETs for hot-swap and redundant configurations, active current sharing, and an I2C management interface for status monitoring and control. Status is also provided via front panel LEDs. The power supply operates within a temperature range of 0°C to 50°C and meets international safety requirements for ITE, carrying CE marking.
Mechanical specifications include dimensions of 302.9mm x 78.0mm x 40.3mm, suitable for rack mounting. Advanced thermal management techniques and a variable-speed fan contribute to reliable operation across a broad range of conditions, while the fan's speed is adjusted for low noise at lower ambient temperatures.
