Dimmer2 gets too warm. Oscilloscope pictures included.





I have a dimmer2 dimming  6x 12W Led downlights which are wired in parallel.

The total power load is max 72W. Each downlight has its own transformer.

The wiring is such that I can't make them separately wired.


Problem: The Dimmer2 gets very warm. Easily hits 45 degrees even outside a wall cavity.


I've captured a crappy photo from my oscilloscope showing the waveform being output by the Dimmer2, with the brightness turned right down low.


I'm not sure why it's getting too hot.


I'd appreciate any help. Cheer + thanks.

72W with leds with low power factor (<0.5) may draw current higher that you can expect.

In this setup it can easily use more than half of dimmer capabilites (1.1A max on output) so 47*C looks ok. 

That is not too hot, by norms it can be a lot hotter.
