This is a high-power electronic voltage regulator, work power up to 2000W, generally can be used to adjust the voltage, adjust the light, adjust the motor speed, or adjust the temperature. In the case of access to the load, we can use it to adjust the AC voltage, adjust the range from AC50V to AC220V. It uses the FR-4 circuit board which can bear high temperatures, the maximum voltage and current is 1200V / 25A.
