PWM Controller YYAC-3S AC 220V

The YYAC‑3S PWM Controller Module (AC 220 V) is a compact, opto-isolated thyristor-based module for controlling AC voltage via PWM signals. It supports high-power devices up to 3 A and is ideal for applications like light dimming, motor speed control, temperature regulation, and voltage adjustments using microcontrollers (3.3–5 V PWM input). Its small size and multiple function make it versatile in both DIY and industrial builds.
