RGBW with led strip: connection question

[jeje87a 0]

Hi,

I need to connect 2 10m led strip which require 5A each at 12v (power from each of the 2 adapter I have).

If I am not mistaken the RGBW can take these 2 strips by itself (10A at 12v for both led strip should be sufficient, which is less than 144w max that the controller can take).

My question is about how to connect everything.

Should I connect both adapters to the RGBW fibaro switch (so both adapters sending 5A to the fibaro controller 12v and GND) and then:

- the 12v from one adapter to 1 led strip and the other 12v to the other led strip.

- RGB from the fibaro controller to both led strips (so 2 cables coming out of each R,G and B and connected to each led strip)

Would this setup work?

Thanks for your help.

Just connect 12V from each adapter to one strip, bridge their GNDs and connect them to RGBW's GND. Also power RGBW from any of them. But notice, that 5A for channel is big value, close to maximum ratings and it is not advise to use such high loads

Thanks for your answer

I thought the maximum was 144W so 12A at 12v unless I missed something?

I only intend to send 10A@12v or 120W

Yes, but there is also limitation for single channel and 5A is value close to it.

Thanks for your answer.

Something that is not clear to me:

- if I connect both supply I will send 10A@12V to the controller. If I select blue only on the strip, does it mean it will try to send 10A via blue only (and hence break)?

- If I select a mix of the RGB it will be 3.33A per channel?

Sorry if the question sounds silly but I want ot make sure that I have the correct understanding.

It depends on strip you will use, current drain is not always 100% - that means 10A will be used only when LED strip need it. If you are not sure about your setup you should consult specialist electrician about it.

I measured it yesterday and the 10m only takes 1.8a when I select white (full power)

On that basis there should not be any problem with the fibaro RGBW

Hi jeje87a

did you manage to get it working ? if so, are you able to post a basic diagram of how you wired it ?

i also would like to wire 2 LED strips to a single RGBW controller ...

Thanks in advance

I picked a 24V LED strip in my system, just to keep the current lower. A single power supply with two LED strips connected in parallel after the dimmer.

Worked great, I checked how much the strip needed at most (white + max brightness) and it was only 1.7A.

Connected as follows:

- power supply to RGBW

- power to the 12v on each strip (parallel)

- RGB of each strip connected to the RGBW

So both strips are connected to the dimmer and to one power supply only (5V 12a).

It works great (except the RGBW dead node every few hours which is annoying).
