I have a system where there is a "master dimmer" (an 800W dimmer designed for household lighting). From that master dimmer, I have a few SSRs switching 40W incandescent light bulbs.
The idea being you can control the brightness of all of the lights with one dimmer.
However, the SSRs are only switching reliably when the dimmer is on full brightness, or set to very dim. Dimming mid way results in some lights just 'sticking' on.
Could the dimmer be messing with the zero crossing detection?
Any help would be much appreciated
Edit: this is the SSR being used
