PFC Inductor (3)


SANHE-ED29 is mainly used to supply power to control unit of microwave oven and to convert the mains input into the working voltage required by the power board to achieve signal control, motor drive, data storage, protection, etc. At the same time, SANHE-29-004 is equiped with temperature protection on account of large current output. When abnormal overheating occurs, it will automatically disconnect to prevent danger.
