4000W SCR Voltage Regulator AC 220V Speed Controller Dimmer

The 4000W SCR Voltage Regulator AC 220V Speed Controller Dimmer is a high-power AC control module designed to adjust the effective power delivered to compatible 220V AC loads. It uses SCR/thyristor phase-angle control and a rotary knob for smooth manual adjustment. The module can be used for light dimming, heater temperature control and speed control of suitable universal or AC motors. Its metal enclosure and heatsink help dissipate heat during operation.
