ColorSource ThruPower dimmer as relay?

Hello dear enlightened humans,

I would like to use some channels of a 24 channel ColorSource Dimmerpack as switches and as far as I understand the Datasheet it says for itself that it can be used for dimming operations or as relays. Now when we tried it and configured some channels as switches and had a Look Solution Unique 2 hazer on the outlet it looked fine when switched on but the display of the machine was flickering when it was switched of. That scared us enough to plug it into a regular AC outlet instead.
Now I would like to know what the problem with that could be. When I bring up my channel for the switch I do hear a click in the Dimmerpack.
Should there actually be an opened contact when switched of? Can´t be when there´s something coming through right?

Right now I don´t want to use it not knowing better if our equipment can be harmed or not.

I´m thankfull for any help!

P.S.: We had no multimeter on any outlet so far...

  • Hi,

    I think I know what the problem your having is!

    You are correct that ColorSource thru-power circuits can be configured as ether dimmers or relays. But to ensure that the rack complies with CE requirements there is a suppression cap across the relay. In some circumstances with very low wattage devices, this can cause a device to try and power up. We normally only see this will light LED loads of a couple of watts or with mirror ball motors. 

    There are two ways to overcome this problem. The 1st is to dummy load the circuit with an incandescent load to counteract the small leakage current from the suppression cap. The other is to bypass the suppression cap completely. This should only be done by a commissioning engineer or an electrician, as it does require a jumper setting to be changed inside the dimmer.

    See this support article for more details:


  • Thank you very much for the quick response!

  • I think the relevant question for us right now is if we´re getting trouble using a "non-legal" product if it´s not fulfilling CE requirements any longer if we bypass the suppression capacitor.
    But I think we will work that out with our distributor who did the installation as well and will use the load ´till the decision is made.
    As said before: Thank you very much!
