ITEM NAME:AC 220V 4000W Motor Speed Controller Governor, SCR Speed Driver Board, Elec G7A3 AC 220V 4000W Motor Speed Controller Governor, SCR Speed Driver Board, Elec G7A3 Operating voltage: AC 220V Max Power: 4000W (Connected resistive load) Voltage Regulation: AC 0V - 220V Adjustable AC 220V 4000W SCR electronic voltage regulator Dimming dimmer Thermostat Governing Speed controller Color: picture color material: plastic Size: (shell) 85*55*38mm Usage: This product is Connected to 220V AC input, The output is connected to the electric wire or electrical appliances, Rotary potentiometer rotating rod, Can play speed, pressure, temperature control effect Application: This product uses the new two-way High Power SCR, Because the design of the current max up to 20 A A good solution to cool down the situation in the electric wire Resistance is too small to cause over-flow problem; Can easily adjust the output voltage 0-220V Such as:Furnace,Hot water heater tune,Lamp dimming,Small motor speed,Electric iron，thermostat and so on. So as to achieve dimming, thermostats, adjusting the voltage effect. Can be used for electric power appliances use less than 4000W Inductively or capacitive load power should be reduced, the regulator is equipped with two-way high-power thyristor, potentiometers are with nuts and thick oversized radiator with aluminum shell Note: Note that the load can not exceed the maximum power, otherwise it will burn modules and appliances; Try using a resistive load; Inductive, capacitive load power to stay for more than half margin. packing including： 1x AC 220V 4000W High Power SCR electronic regulator
