The PFE1500-12-054RA is a 1500 Watt AC-DC power-factor-corrected (PFC) power supply from Bel Power Solutions. It converts standard AC or HVDC power into a main output of 12 VDC, making it suitable for powering intermediate bus architectures (IBA) in high-performance servers, routers, and network switches.
Key electrical specifications include a universal input voltage range of 90-264 VAC and 180-350 VDC, a 125A output current, and 92% efficiency. The unit supports hot-plug capability and parallel operation with active digital current sharing. It also features an always-on standby output, programmable for 3.3V/5V (16.5W) or 12V @ 3A (36W).
For enhanced control and monitoring, the PFE1500-12-054RA includes an I2C communication interface supporting Power Management Bus and PSMI protocols. Protection features include over-temperature, output over-voltage, and over-current protection. The power supply has 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 meets international safety standards, including 62368, and displays the CE-Mark. It is designed for ITE (Commercial) applications and features a fan for cooling. The unit is RoHS3 compliant and has an MSL of 1.
The input voltage range is 90-264 VAC or 180-350 VDC.
It is designed for rack-mount installation.
The operating temperature range is 0°C to 45°C with derating.
The output is 12 VDC at 125 A, providing 1500W.
Typical efficiency is 92%, reaching 94% at half load (80+ Platinum).
It supports I²C communication with Power Management Bus (PMBus) and PSMI protocols.
Protection includes over temperature, output over voltage, and overcurrent.
