4 Channel AC Light Dimmer Module Arduino

Module contains four Triacs with zero-cross detector
for programming the intensity of incandescent lamps, heating elements or fan speed controlled through a micro-controller.

Working voltage from 110v to 240v.
Auto detect 50Hz or 60Hz.
Zero-Cross detection (with zero/cross output pin SYNC).
Compatible with any ARDUINO, RASPBERRY boards.

Low voltage side and high voltage side is completely isolated.

Dimensions of the PCB 110mm x 50mm (4.33inch x 1.97inch). Four mounting holes diameter 3.2mm (0.13inch).

Connected LOAD power for each channel 1500W long-term and 3500W short-term.

NOT appropriate to change the brightness of fluorescent lamps !!!

is it possible to have the dimness controlled remotely by having wifi module?

Thanks video. However, I was being misunderstood by the title, that's mean wrong title.
whether can you control level light (dimmer) bulb1 and bulb 2 and bulb3 and bulb4 seperate, not automatic?

Hello Sir Really Super Project, Sorry but one doubt. this project properly work or not? please reply me sir

[adnestrada]

Can I connect two bulbs to the same channel?

[SaeedAhmed-ixnm]

from where i can buy this module?
I want to buy this module and I will be using it with Arduino MEGA. I want to change the Load with time. Maximum Load will be 500 W Heater so around 5 Amps 220V 50 Hz.
Can I use it as variable resistor to control the load of 500W? Please reply me which module i should buy because on your website you have alot of options.

Thankq Sir,
Please send more example to Arduino sketches or youtube videos.

don't work in my Arduino uno R3, others code work Fine but this code all time the lamp is off. Need some Help.


*
* Demo Arduino code for 4CH AC DIMMER MODULE
*
* AC LINE FREQUENCY - 60HZ !
*
* Variables for dimming - buf_CH1, buf_CH2, buf_CH3, buf_CH4 !
*
* Variables have range 0-255. 0 - Fully ON, 255 - Fully OFF.
