* Referred to 40°C max ambient temperature. Dependently to work conditions, actual max power could be higher than rated. 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)
