The Bel Power Solutions PET800-12-074ND is a high-performance 800 Watt DC to DC power supply designed for intermediate bus architectures in servers, routers, and network switches. It converts a -40 to -72 VDC input voltage into a regulated +12 VDC output.
This front-end power supply utilizes a digital control architecture for enhanced efficiency, control, and functionality, achieving up to 94% efficiency at 50% load. Key electrical specifications include an 800W power rating, a 12VDC output voltage, and a 65A output current. It also features an always-on 24W standby output.
The PET800-12-074ND is built for reliability and high availability applications. It supports hot-plugging and parallel operation with active current sharing. The unit has a compact, high-density design with dimensions of 185 x 73.5 x 39 mm, suitable for rack mounting. It operates within a temperature range of 0°C to 50°C and meets international safety standards, displaying the CE-Mark.
Digital controls and Power Management Bus communications protocol allow for advanced control, programming, and monitoring, including input/output voltage, current, power, and internal temperatures. Protection features include over-temperature, output over-voltage, and over-current protection. The supply is fan-cooled with speed adjusted automatically by the DSP controller.
