PET750-12-050ND

The Bel Power Solutions PET750-12-050ND is a 750 Watt DC to DC power supply designed for high-performance and reliability applications such as servers, routers, and network switches. It converts a wide input voltage range of -40 to -72 VDC into an insulated main output of +12 VDC.

This power supply utilizes a digital control architecture for enhanced efficiency, control, and functionality, achieving up to 94% efficiency at 50% load. It features an always-on 5V/3A/15W standby output, hot-plug capability, and parallel operation with active current sharing. The compact dimensions of 300 x 50.5 x 40 mm and a high-density design of 20.5 W/in3 make it suitable for integration into various systems.

The PET750-12-050ND includes protection against over temperature, output over voltage, and over current. It also features a status LED with fault signaling and a Power Management Bus communication interface for control, programming, and monitoring. The unit meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).

Designed for demanding environments, this DC-DC converter is fan-cooled and ideally suited for integration with a matching airflow path. An active OR-ing device on the output ensures no reverse load current, making it suitable for redundant power systems. The DSP controller manages fan speed based on power demand and supply temperature, with override capability via the I2C bus.
