The dimmer works perfectly. All channels can be controlled as expected and regulate cleanly between 0-100%. Something unusual, but quite logical: 100% = light off; 0% = light on. I can absolutely recommend this dimmer. :)
I received the product pretty fast and I have tried it. The dimming is far better and smoother than the other products I've been using from AliExpress for example, it is very easy to use and connect it. I strongly recommend it.
The designer has made an excellent work with this dimmer. The PCB layout is very neat, the silkscreen clearly shows the components and their values. The assembly is professional. All pieces of this product demonstrates superior craftsmanship. Get a CE and I am happy to design in this dimmer into my next commercial project!
I was looking for a dimmer which I can control with an Arduino by using its PWM output and simple code. If you search the internet there are not many products like the one sold by tindie on the market. The shipment was quick and the pcb made an excellent impression. AC high voltage and low voltage section clearly separated only linked with optocouplers. I used the sample code provided on the product page and the dimmer worked instantly as it should. I use the dimmer to control the power of a spotwelder made of a converted microwave oven transformer where an Arduino controls the pulse length and the power (inductive load). Everything works perfect now, by means of controlling power and pulse length I can weld a wide range of sheet metals of different thickness.
