Based on TDK-Lambda's popular FPS1000, HFE1600 and HFE 2500 plug-in, hot swap power supplies, the RFE models have terminal block and bus bar connections and can be used without a rack. This allows these 1000W, 1600W and 2500W power supplies to be mounted close to the load, and being just 41mm high, be located where space is at a premium. Available with 12V, 24V, 32V and 48V outputs, the outputs can be easily paralleled to provide more power. I2C and PM Bus (RFE1600 & 2500) communication are available as an option.
