_x000D_ 1. The module adopts the imported silicon controlled rectifier, with the voltage withstand up to 1200V 2. The voltage regulator has a wave peak voltage absorption circuit to effectively protect the high-power SCR for longer life 3. The voltage regulator can adjust the output low voltage through the precise multi turn potentiometer 4. St original imported trigger diode 5. High quality CBB capacitor, withstand DC withstand voltage 630V 6. All potentiometers are equipped with nuts and can be used without any components 7. Module size: 60mm * 48mm * 28mm Input voltage: AC 220V Voltage regulation: 50v-200v Maximum power limit: 2000W Maximum current limit: 25A Note: the module is connected with 220V AC voltage, so pay attention to safety during commissioning Product application Connect the product in series in the circuit of desk lamp or electric appliance, (i.e. disconnect any one of the live line or zero line of desk lamp and electric appliance, and connect the two lines of the "product") rotate the rotary rod of potentiometer, which can play the role of light and shade adjustment, speed regulation, voltage regulation and temperature regulation. It is very convenient to use. The product is applicable to: use the new bidirectional high-power thyristor, the current can reach 25 A It solves the problem of over-current caused by the electric furnace wire, the
