It is an electronic device that regulates and varies AC voltage (up to 220V) and power output (up to 4000W) to control the speed of motors, brightness of lights, or temperature of heating elements by reducing or increasing the effective voltage supplied to the load.

Precautions and instructions for use
1.When the machine is empty, the measured output voltage is a virtual voltage, and it must be connected to a load of more than 20W to measure the correct output voltage. 2. Input AC, and the output is also AC, not DC.
3.The 4000W mentioned above refers to the limit power when working in a resistive load. The inductive load is 1/3 of the resistive load. The resistive load refers to the tungsten filament lamp, heating wire, etc., and the inductive load refers to the series motor. Etc., use circuit board electronic products with caution.
4.The metal shell of this product must be safely grounded
