2000W AC Motor Speed Controller 50‑220V 25A Adjustable Motor Speed Controller Voltage Regulator Description: This controller uses novel bi-directional high-power SCR. It can be very convenient adjust the current up to 25A, and solve the over current problem of the heating wire resistance is too small in the case of cooling causing good. The output voltage is adjusted anywhere between 50V-220V for use with electrical appliances. It can use to such as electric stove, water heater tune thermal, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect.
