The B120SJ48-402FT-00 is a fully digitally controlled high efficiency high power density bidirectional AC-DC converter using totem pole bridgeless circuits and full bridge LLC converters based on third-generation power semiconductor devices. The rectifier mode supports the full range of AC input, the output voltage is 48Vdc, and the voltage regulation range is 35VD-56VDC. The inverter mode supports 35VD-56VDC input and 120Vac output. The maximum power of the rectifier mode is 1800W, the maximum power of the inverter mode is 4000W, and the maximum efficiency is >95%. Fan forced air cooling design, low noise, higher reliability. The bidirectional AC-DC converter has over voltage, under voltage protection, over current, short circuit protection and over temperature protection on both AC side and DC side.
