Dimmer overcurrent and/or dimming up -> dying or blinking erratically



I have a FGD-212 controlling a LED-strip via a hide-a-lite led-driver. Lately it has started to act up.

Two scenarios and lately almost always the first one only:

1. When turned on for the default of 1% power it lights up fine but after a few seconds it starts to dim up to 99% and and then shuts down due to over current.

2. After a few hours burning the strip starts to flicker, blinking erratic for minutes and then turns of due to over current


The strip is two 5 meter 12 volt Amazon-strip from Subosi. Divided into two 3 meter long sections, totalling 6 meters and 48 watts at 100% power.

The LED-driver is a Hide-a-Lite SLD75-12VL-E

As I have no other driver, strip or dimmer to try with at this point I am curios if someone knows the most likely source of the problem? Driver, strip or Dimmer2 ?


The FGD-212 is reset and I have run start up calibration successfully several times. I have tried a lot of different settings on parameters I think could affect performance. 


I am running HC3 latest firmware (not beta). Strip is super bright and therefore 1% power is sufficient for the effect lightning I use it for. 

Edit: Looks I have updated the HC3 to 5.141.59 (beta) unknowingly but issue has been around for several weeks now...

    Might have found one error on my own reading the specs for the driver. It states min load is 12 watts. I suppose 1% of 48 watt is low then :)

    Interesting it has been working for over a year ... 

    Should I consider putting a dimmer on the 12 volt side instead? I.e adding a resistor leaving some heat load instead but getting the LED-driver to use some more power? Actually I could then run the FGD-212 as on/off only and lock the dimming level on the 12 volt side. ( I never need to adjust dim level thinking of it)

  • Problem solved. When trouble shooting I found a second led-driver connected. This led-driver is not used so likely a mistake from the installer thinking it could be operated from the same dimmer2.  It was put there to have everything prepared for future light installs. I disconnected it, ran auto calibrate again and now all works fine. I see now the led-strip pulls 7-8 watts at 1% level. Working fine despite the 12 watt low limit.
