PFE1500-12-054NDS412

The Bel Power Solutions PFE1500-12-054NDS412 is a 1500-watt DC-DC front-end power supply designed for high-performance servers, routers, and network switches. It converts DC input into a main output of 12VDC, suitable for intermediate bus architectures.

Key features include a typical efficiency of 94% at half load, a wide input voltage range of -40 to -72 VDC, and an always-on standby output that is programmable (3.3V/5V) or fixed (12V). The unit is hot-plug capable and supports parallel operation with active digital current sharing. It boasts a high density design of 35 W/in³ and a compact form factor measuring 321.5 x 54.5 x 40.0 mm.

This power supply integrates an I2C communication interface for control, programming, and monitoring, along with protection against over-temperature, output overvoltage, and overcurrent. It also includes 256 Bytes of EEPROM for user information and status LEDs for OK and FAIL signaling. The PFE1500 Series meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).

Designed for reliability and high availability applications, the PFE1500-12-054NDS412 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.
