The Bel Power Solutions PFE1100-12-054XD is a 1100 watt DC to DC power supply designed for intermediate bus architectures in high-performance servers, routers, and network switches. It converts a DC input voltage range of 40-72 VDC to a main output of 12 VDC.
Key electrical specifications include a nominal output power of 1080W, nominal output current of 90A, and high efficiency up to 94% at 50% load. The unit offers features such as an always-on 16.5W programmable standby output (3.3/5V), hot-plug capability, and parallel operation with active digital current sharing. It also includes overtemperature, output overvoltage, and overcurrent protection.
Designed for reliability, this power supply has a high density of 25.6 W/in3 and a compact form factor measuring 321.5 x 54.5 x 40 mm. It incorporates an I2C communication interface for control, programming, and monitoring, supporting PSMI and Power Management Bus protocols. The unit also features 256 Bytes of EEPROM for user information and status LEDs for output monitoring.
This power supply meets international safety standards and displays the CE-Mark for the European Low Voltage Directive. It is suitable for applications in ITE (Commercial) environments.
