The 220 V AC 2000 W SCR Voltage Regulator is a high-power AC control module designed to regulate output voltage and power delivered to AC loads. Using phase-angle control with SCR (Silicon Controlled Rectifier) technology, it allows smooth adjustment of power for resistive loads such as heaters, lamps, and universal motors. This module is commonly used in dimmers, speed controllers, temperature controllers, and industrial power regulation applications.
