Fibaro Dimmer module melt down

[budda 5]

I've had the Fibaro Dimmer module controlling 4 x MR16 halogen lights in my bathroom for over a year - without problem.

About a month ago 3 of the 4 12V transformers packed up within the space of about 1 week. The 4th transformer that continued to work was one I had replaced a few years ago.

So the dimmer module only had 1 working transformer and MR16 bulb connected this month.

Whilst I was hoovering the hallway I kept smelling hot plastic as i moved around. After a lot of sniffing I unscrewed my light switch to discover the Fibaro had melted the corner of its casing and could see a spark/arching from within the unit.

In the corner next to the 'L' connection block terminal I can see inside the unit where it looks like a component casing has popped/cracked too.

I immediately turned off the mains power and removed the unit from the light switch. I'm just glad I noticed it during the afternoon and it wasn't sat there cooking through the night!

I have more of the same Dimmer modules installed and so far have not experienced the same problem, but they were bought around the same time so maybe from the same batch.

Hi guys please give me an advice about the following:

We are going to install like 150meters of RGB led strip 12volts. They will be dimmable and the power consumption will be like 800W. The transformers are dimamble DALI led drivers. The total wattage for 1 dimmer is 500w and i am planning to install like 1 dimmer for 2 transformers in order not to burn the dimmers. So for 7 transformers it will be like 4 dimmers which will be associated in the HC2. When you dim 1 of them, the others will dim aswell. What do you thing about the idea (the number of dimmers and transformers and the association in the HC2)? Any ideas and suggestions are going to be welcomed!

 

i'd open this question as a new thread about RGBW module rather than tacking on to the end of the faulty dimmer module discussion. Might never get seen.

Has this issue been resolved with the FGD212??

it says it may handle leading and trailing edge
