Description

The SCR (Silicon Controlled Rectifier) / Thyristor AC Voltage Regulator Module is a high-power AC voltage control board designed to regulate the power supplied to AC loads. Using phase-angle control, the module provides smooth and precise adjustment of AC output voltage through an onboard rotary potentiometer. Large aluminum heatsinks ensure efficient heat dissipation, allowing reliable operation with medium to high-power loads.

This module is suitable for controlling the brightness of incandescent lamps, heating elements, soldering irons, universal AC motor speed, and various industrial or laboratory applications.
