The HK9990 LED dimmer is a universal DC regulator designed for controlling the brightness of LEDs and lamps, as well as the speed of DC motors. The device is based on a PIC microcontroller, providing stable and reliable operation.
Brightness or motor speed is adjusted using a potentiometer. A dedicated push button enables smooth power on and off, protecting the load from sudden current surges and ensuring soft operation.
The dimmer operates on direct current (DC) with a supply voltage range from 8 to 24V, depending on the connected load. The maximum output current is up to 2A when used without a heatsink.
This module is suitable for LED lighting systems, decorative lighting, electronic projects, models, and small DC motor control applications.
