Feature:1. HIGH POWER SCR: Using bidirectional high power SCR, the current is 25A, which solves the overcurrent problem and can be adjusted arbitrarily between AC 50220V.2. WITH POTENTIOMETER: Rotating the potentiometer to adjust the brightness, speed, voltage, temperature, etc. of the motor, can be used for home appliances such as lamps.3. EASY OPERATION: Can be used by electrical appliances with a power less than 2000W, the potentiometer is equipped with nut, which can be used without adding any components.4. CIRCUIT PROTECTION: The voltage regulator is equipped with a peak voltage absorption circuit to protect high power thyristor, ensuring stable performance and longer service life.5. APPLICABLE SCENES: Suitable for heat regulation of water heater, light regulation of lamp, speed regulation of small motor, temperature regulation of electric soldering iron, etc.Specification:Item Type: Voltage RegulatorInput Voltage: AC 220VVoltage Regulation: AC 50V-220VMaximum Power: 2000WMaximum Current: 25A.Package List:2 x Voltage Regulator
