Features: Equipped with new type of bidirectional large power thyristor rectifiers, current can reach up to 80A, effectively solve the problem of overcurrent in electric furnace wire caused by low resistance during the cooling process. It can easily adjust the output voltage within the scope of 0-100% (nonlinear) to power electrical equipment. The design features a large and thick heat sink to enhances the heat dissipation effect. It can be adjusted through button, which is much more stable than a potentiometer. Can use as a power adapter for large electrical equipment with less than 10000W, sufficient for household appliances or small factories. Widely use as a thermal controller for electric furnaces, water heaters, dimmers for lamp, speed controllers for small motors, or temperature controllers for soldering irons.
