AC 220V 2000W SCR Voltage Regulator Dimmers Speed Controller Thermostat
[AC Motor Driver] 2000W AC 220V SCR Thyristor Voltage Regulator – Motor Speed Controller & Dimmer The 2000W AC SCR Thyristor Voltage Regulator is a high-power electronic controller designed for adjusting AC voltage to control light brightness, motor speed, heating temperature, and other suitable AC loads. It uses a high-power bidirectional silicon-controlled device and an onboard potentiometer for convenient voltage adjustment. The controller can be connected in series with a compatible AC load and adjusted using the rotary knob. It is suitable for applications such as electric furnaces, water heaters, lamps, small motors, electric irons, and other compatible resistive or motor loads. ⭐ Key Features 2000W maximum advertised power AC voltage regulation 90–220V AC input Adjustable output voltage: 50–220V AC High-power SCR/thyristor design Onboard adjustable potentiometer Suitable for light brightness control Suitable for motor speed control Suitable for heating temperature control Compact design Potentiometer includes fixing nut No additional external control components required for basic operation 📋 Technical Specifications Product Type: AC SCR Voltage Regulator Controller Type: Thyristor / SCR Regulator Input Voltage: 90–220V AC Adjustable Output Voltage: 50–220V AC Maximum Power: 2000W SCR Rating: 25A Recommended Power for Voltage Adjustment: Up to approximately 1000W / 5A Recommended Current for Electrical Machines: Up to approximately 3A Control Method: Rotary Potentiometer Material: Plastic / Metal Dimensions: 48 × 55 × 27mm Weight: Approximately 41g Application: AC Voltage / Speed / Brightness / Temperature Control 🛠️ How to Use Connect the controller in series with the compatible AC load according to the input and output markings. After making sure all connections are secure, rotate the potentiometer to adjust the output and control the connected load. For resistive loads such as lamps or heaters, the controller can be used for brightness or heating control. For compatible small AC motors, it can be used for speed adjustment. 🔧 Applications AC Lamp Dimmer Light Brightness Control Small AC Motor Speed Control Electric Furnace Control Water Heater Control Electric Iron Control Heating Element Control Temperature Control AC Voltage Regulation DIY AC Control Projects 📦 Package Includes 1 × 2000W 220V SCR Thyristor AC Voltage Regulator / Motor Speed Controller ⚠️ Precautions This module works with potentially lethal AC mains voltage. Installation should only be performed by a qualified person familiar with AC electrical systems. Do not touch the board or terminals while powered. Do not exceed the specified voltage, current, or power ratings. The 2000W rating is a maximum advertised rating; actual safe continuous power depends on load type, cooling, enclosure, and operating conditions. For voltage adjustment applications, the supplied specification recommends approximately 1000W / 5A or below. For electrical machines, the supplied specification recommends 3A or below. Provide adequate ventilation and heat dissipation at higher loads. Use appropriate fusing and electrical protection. Ensure all wiring and connections are properly insulated and secured. This type of controller is not suitable for every AC load; verify load compatibility before use.
