Led drivers burn while connected to Dimmer2

Question

Hi all, 

 

I have 5 Philips garden LED lights installed. All connected to a Fibaro dimmer 2 module.

According to the Philips manual, these LED lights support  dimming.

 

When I initially dimmed the leds in HC2, this worked fine. However, after several hours (20?) the lights stopped working .

In HC2 I got a red notification (overcurrent?) and when I opened the led driver (SLT12-700IF) it smelled like burned PCB.

 

I expected that the way light gets dimmed by dimmer 2 differs to the way this is done by a conventional LED dimmer so I disabled dimming in the settings of this particular Dimmer 2.

Still I suffer that the lights stop working and I get a notification in HC2. Each time, the led-driver smells like burned PCB and after I have swapped that specific led-driver , the issue is gone for some time. 

 

Ugly thing is that I now have already replaced 4 drivers in ~2yrs time and I have no clue what I can do against this.

I havent tried another Fibaro module yet nor did I test if the issue is gone when I remove the Fibaro module completely.

 

Does anyone understand why I suffer this issue? Is the SLT12-700IF not compatible with Fibaro, even when used without dimming?

Any setting in Dimmer 2 that I can to change to prevent this issue?

 

Regards,

Jules

SLT12-700IF is not dimmable, and might (as you already recognized) got destroyed when controlled with dimmer. You might set Startup time to 0, min to 98, max to 99, non-dimming and so on … but honestly, why you just not buy dimmable driver and replace these cheap SLT12-700IF?

  • Hi Tinman,

     

    I set my dimmer settings exactly as you suggested. I did not order dimmable drivers as I dont know if they exist in the same dimensions. The drivers are mounted in a plastic box that is mounted in the philips armature, so the dimensions/volume is fixed.
     

    Do you happen to know what dimmeable driver I could order with same dimensions? 
    That would definately be a better solution.

     

    thanks!
