* Referred to 40°C max ambient temperature. Dependently to working conditions, actual max power could be higher than rated. Working with actual output power very lower than rated in combination with some input/output voltages, the power factor correction could result unsatisfactory. Contact our technical service for more info. Output power is related to each inductor (doubled on two phase interleaved configuration).
** With Vdcout lower than 400Vdc, to have rated min. frequency higher than 25KHz, derate input voltage to 253Vac max (Pout 360W) or output power to 250W max (85...264Vacin)
