AC Light Dimmer Module

AC Light Dimmer Module

The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. This Module contains a Triac triggering coupled with zero-cross detector mechanism for programming the intensity of incandescent lamps, LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller. This Module compatible with any MCU, Arduino or Raspberry boards.

Warning!

This circuit is attached to a 110-240 Voltage. Do not build this if you are not confident about what you are doing. Unplug it before coming even close to the PCB. The cooling plate of the Triac is attached to the mains. Do not touch it while in operation. Put it in a proper enclosure/container.
