arduino AC 220V 2000W SCR Voltage Regulator Dimmer Speed Controller Thermostat Electronic Components Electronic Hobby Kit

This is a high power electric voltage regulator, work power up to 2000W and at 200V AC, usually can be used to adjust the voltage, light, motor speed, and temperature. In the case of access to the load, users can use it to adjust the AC voltage, adjust the range from AC50V to AC220V. The device comes with reverse polarity protection and high current protection. It uses the Fr-4 circuit board that can bear high temperature, and 220V/25A voltage/current rating. The module is equipped with a peak observation circuit that can effectively protect the high-power thyristor, making it a longer life.
