Hello forum!
I am a beginner in electronics and for a lighting project I bought a dimmable trafo and a touch dimmer with the hope to be able to combine these.
The trafo is a MeanWell LDB-600L, that is a 600mA constant current trafo with a "DIM" input that takes either a PWM signal (100-1kHz) or a 1-10V signal (Reference: https://www.meanwell.com/Upload/PDF/LDB-L/LDB-L-SPEC.PDF).
The touch dimmer has a 12V input and some undefined output which I assumed would transform the input voltage to 1-12V (possibly via PWM).

I have an input of 12V available to me and just tried to string this together, but to no avail. The touch dimmer works differently than I expected. It works great with 12V LED strip but without a consumer the output voltage only dims from around 12.3V to 12.7V. I think that is why the trafo does not react at all to the touch dimmer input and just works at seemingly a 100%. With the LED strip attached tto the touch dimmer the voltage ranges from 6.9V to 10.9V which produces a nice lighting result but the lower voltage is still much higher than I anticipated.
I would love to keep using these touch dimmers because I also want to dim two sets of LED strip and place the dimmers next to each other. It would be nice if they have a consistent look.
Is there a way that is not too complicated to achieve this?
Thank you all in advance
