Features :
The use of the new bidirectional high-power thyristor, because the current can reach 41A, which solves the problem of overcurrent caused by the electric resistance of the electric furnace wire being too small in the case of cooling.
It is very convenient to adjust the output voltage and adjust it between 0V-220V for use by electrical appliances. Such as: circuit / water heater heating, lighting dimming, one-way motor / exhaust fan / blower / axial fan speed control, electric Luo iron temperature adjustment, etc., to achieve dimming, temperature adjustment, speed regulation and pressure regulation effect.
The utility model can be used for large electric appliances with electric power less than 2000W. Since the power is already large, the general household appliances or small factories are enough to use.
Equipped with two-way high-power thyristor, the potentiometers are equipped with nuts, which can be used without any components, which is very convenient and practical.
