Using FGS-224 to control a 12V LED stripe - How to?


Question

Posted

I want to use a FGS-224 Double Smart Module to control a 12V DC- monochrome (= white) LED stripe, but can't get it to work.

The FGS-224 is connected properly to the 12 V DC outlets of the transformer, and is working fine - it's properly identified within my Fibaro HomeCenter 2, and when I switch it, you can clearly hear the actuacting click also.

 

But for some reason, it does not switch any power to the other ports, or I am not connecting the load (= the two connectors from the LED stripe) properly. 

How do I have to connect those two cables to the FGS-224? I thought when I connect the "+" cable of the LED-strip to "IN" and the "-" cable to either "Q1" or "Q2", then I should be able to switch the LEDs with the FGS-224 - but I don't get any power output on these ports.

 

What am I missing here, in this simple case? How do I have to connect the two cables from the LED-strip to the FGS-224 to make it work?

// I thought when I connect the "+" cable of the LED-strip to "IN" and the "-" cable to either "Q1" or "Q2".

So send the source to the short circuit!!!

 

I have 2 warnings for you.

1) The module is defined for 24-36VDC power supply, so if you supply it with 12VDC, it is a coincidence that it works.

2) If you switch low DC voltage (12VDC) with higher current, the contacts wear out (burn).

    Thank you... 

     

    Concerning your warning #1:

    The whole circuit is running on 12V DC, so you warning does not apply. 

     

    For warning #2: I've read on multiple sources that the FGS-224 also works fine and stable with 12 V DC, in this is what I also observe. 

     

    "So send the source to the short circuit!!!" - this I don't understand. 

    Could you maybe just explain which cable to connect where?

    Maybe we don't understand each other.

    Point 1) the supply voltage for the module is 24VDC-30VDC, or 100VAC-240VAC.

    So if you power the module from 12VDC, it's a coincidence that it works.

     

    Point 2)

    if you look at the diagram in the manual, the IN terminal is internally connected to the Q1 and Q2 terminals.

    From the description, it's not entirely clear to me how you connect the power supply and how the LED.

    A) So if you connect the + source voltage to IN, and the - source to Q1, the source will short circuit when the output is turned on

    B) if you connect the + LED to IN and the - LED to Q1, you won't send any voltage to the LED even when the output is turned on.

     

    So correctly connect the - LED to the - source, + LED to Q1, + source to IN.

    Connect +24VDV to L and -24VDC to N of the module.

    Thank you very much... still doesn't bring the LED to light, so I guess the module does indeed not work properly on 12V.

    Would you have any recommandation for me for a different switching module that is good for 12V DC instead?

    I took the Fibaro because I couldn't really find anything else :(

    I would recommend another, more standard solution.

    Power the module with 230VAC, connect the primary power supply to the outputs, and only connect the secondary power supply (12VDC) to the LED.

     

    Another option is to use a module FGRGBW-442, which is a directly powered module from 12VDC and contains up to 4 channels for single-color LEDs/lights, or R-G-B/W combinations.

    Thank you very much for your help!

     

    I finally got it to work, by using a Shelby Qubino Wave 1 switch, which is capable of 12 V DC - with that, all works fine.

    Again, thanks for supporting!
