Accipies plenam pecuniam redditam post receptionem et inspectionem. Sumptus missilis non redditur.Contacta nos: service@roymall.com vel Whatsapp: +8619359849471This 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.The output voltage is adjusted anywhere between 0V ~ 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.
Attention:
Load does not exceed the maximum power, otherwise it will burn module and electrical appliances;use the resistive load as far as possible; reduce inductive and capacitive load power greatly. (it is best to leave more than half of them)
