High-efficiency rack power supplies support parallel and redundant operation

February 3, 2026 By Puja Mitra Leave a Comment

The HFE3500 rack mount power supply series from TDK-Lambda is a 1U, 3500 W AC-DC power solution designed for parallel and hot-swap operation in industrial power systems. The series supports 24 V or 48 V outputs, operates from an 85–264 Vac input range, delivers up to 94% efficiency and includes PMBus™ (I2C) communication, current sharing and internal ORing MOSFETs. These features make the HFE3500 suitable for factory automation, ATE, additive manufacturing, RF transmission, base stations and server applications requiring scalable bulk power.
