4000W AC 0-220V 20A Pulse Width Modulator PWM Electric Motor Speed Controller

Use voltage: AC 110V-220V

Maximum power: 4000W (resistive load)

Voltage regulation: adjustable between AC 0-input voltage

Size: 91MMx width 59MM (without handle) total height 34MM

Usage: Input this product to 220V AC, the output is connected to the electric furnace wire or motor appliance, and rotate the potentiometer rotary lever to play the role of speed regulation, voltage regulation and temperature regulation; it is very convenient to use.

This product is suitable for: using the new bidirectional high-power thyristor, because the design current can reach up to 20 amps, which solves the overcurrent problem caused by the electric resistance of the electric furnace wire being too small in the case of cooling; it can be easily adjusted The output voltage of the mains is arbitrarily adjusted between 0----220 volts for use by electrical appliances. Such as: electric furnace, water heater heating, lighting dimming, small motor speed, electric iron temperature adjustment. Thereby achieving the effects of dimming, temperature regulation and pressure regulation. It can be used by large electrical appliances with less than 4,000 watts of electric power. Because of the large power, it is enough for general household appliances or small factories. (Inductive or capacitive load power should be reduced, this regulator is equipped with two-way high-power thyristor, the potentiometer has a nut, and the aluminum shell is thickened and the large heat sink can be used without any components, very Convenient and practical).

Precautions:
?????Note that the load should not exceed the specified maximum power, otherwise the module and the appliance will be burnt out; try to use the resistive load; the inductive and capacitive load power should be greatly reduced (preferably more than half of the amount).
