The HFE2500 can deliver 2500W of output power at high line input voltages, 170 to 265VAC, and 1500W from 100 to 132VAC. Derating is required with an input below 100VAC. The 12V unit can supply up to 200A, the 24V up to 104A, and the 48V unit up to 52A. The efficiency with 230VAC input and at 100% load is 92% to 93%, depending on the output voltage.
