Features [Parameters] The output voltage can be adjusted arbitrarily between 50V-220V, and can be used in conjunction with electrical appliances. 【Efficient】The controller adopts novel bidirectional high-power thyristor, which can also easily adjust the current, up to 25A. [The practical regulator can solve the overcurrent problem caused by the too small resistance of the heating wire under the cooling condition. [Widely used] It can be used for electric furnace, water heater heat regulation, lighting dimming, small motor speed regulation, electric iron temperature regulation, etc., and achieves the effect of dimming, temperature regulation and pressure regulation. 【Reliable Product】Using high-quality materials, it is sturdy and durable and has a long service life. 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.
