    Welcome,

    I am planning a 20m (4x5m) strong (3000 lm / m) LED in the living room. This gives a total of 144W for one 5m section and almost 600W for the whole.

    I'd like to control it and run it through Fibaro, the best for this seems to be Fibaro RGBW but it supports a maximum of 144W at 12V so I would have to connect 4 Fibaro RGBW which starts to be expensive.

    Is there such a device - a bit like a relay only not binary (0-1) but transmitting many values - which I can connect to 0-12V coming out of Fibaro and it will set me transmitting 0-12V but at a much higher current? I cannot connect 600W to a single RGBW module, but I can connect a small 'relay' to which I in turn connect this 600W strip.

    I just don't know if such a thing exists?

    Search under the keyword "RGBW led amplifier", only that I do not see for such a power. You can divide the strips, for example, into three sections with three amplifiers and control everything with one Fibaro controller.

    RGBW amplifier yes, but it won't help with that much power. These tapes need 600W.

    Ideally something like an 'electromagnetic relay' but with a dimming option, so if it's on 12V, if I give it 6V it will set the current flow to 50%, if it's on 9V it will set it to 75%, etc. Then I could connect Fibaro to one side and the other to the 600W. Then I could connect Fibaro on one side and this 600W on the other.

    You run wires from the Fibaro to the three amplifiers and under these amplifiers you connect your tape, so much for the three pieces.
    Unless you don't have the option of pulling the wires.

    Can a colleague throw in the manufacturer's specifications for these tapes? It's just out of curiosity as I can't find any anywhere.

    Tape here: http://www.akb-poland.com/tasma-led-300-diod-smd5630-60lm-5-metrow-144w-biala-zimna.html

    OK thanks! I understand - it should work. I found an amplifier like the one below (powerful but expensive) - I will look for an alternative. I connect Fibaro to the amplifier as input and 3 tapes (4 in my configuration) to the amplifier output. This is exactly what I was looking for.
    https://enterius.eu/produkty/wzmacniacze-led/epm-153-wzmacniacz-led-rgb

    I think that in the end they will be weaker MultiWhite tapes, for example such as https://www.kingled.pl/profesjonalna-tasma-le...00-cieplo-zimna-2700-7000k-14-4w-ip33-1m.html .

    Such a tape has 72W and is 2 colours so if I understand correctly it is 36W per colour.

    So if I connect everything to one RGBW amplifier at 12V, I have 288W total, 144W per colour or 12A per colour - is that correct? Then this Enterius amplifier, which has a maximum load of 15A, will be fine.

    Alternatively, the Fibaro RGBW has a max of 6A / each channel (RGBW) or 12A total, so at 12V 144W total, so I can connect this tape to 2 Fibaro, but the configuration will be more complicated.

    Or such an economical version from allegro? http://allegro.pl/wzmacniacz-sygnalu-30a-360w...b-alu-i7173963592.html?fromVariant=6255914078

    Am I counting correctly?

    I bought a 72W ribbon (14.4w/m, 300led / 5m, 5050) and a 100W LED power supply as a trial and connected to Fibaro RGBW via Smartthings. The connection is on one side only but it is 5m and there is no visible voltage drop.

    After checking the power consumption at 100% my 'smart plug' reports a consumption of 25.4W.

    Why 25W and not 72W?

    This means that I can connect my whole setup above on one Fibaro without RGBW amplifiers, because even 4 tapes will only consume 100W and not 288?

    Your "smart" plug measures the current consumption on the 230V side of the power supply, while you are interested in the current consumption of the LED strip on the 12V side (Fibaro RGBW load). Take a meter in your hand and measure the current consumption of the LEDs behind the power supply.

    .

    From what he showed the plug shows not the current consumption but the power consumption. And upstream and downstream of the power supply should come out similar (upstream a little more due to the efficiency of the power supply)

    Probably the manufacturer of the LED strip overestimated the parameters, or the fibaro shows wrongly, but I would bet on the former.

Topic summary

The discussion addresses controlling a high-power 600W LED strip (20m, 3000 lm/m) using Fibaro RGBW modules, which individually support a maximum load of 144W at 12V. Due to the power limitation, the user considers using multiple Fibaro RGBW controllers or an amplification device capable of receiving a 0-12V control signal from Fibaro and outputting the same voltage range at higher current to drive the entire LED strip. The concept of an RGBW LED amplifier is suggested, typically used to split the LED strip into sections, each powered by an amplifier controlled by a single Fibaro RGBW. However, standard RGBW amplifiers may not handle the full 600W load. A specific amplifier model from Enterius (EPM-153) is referenced, capable of handling up to 15A per channel, suitable for multi-section LED strips. The user also explores using lower power LED tapes (e.g., Kingled Zoomledr 72W, dual-color) to reduce load per channel. Measurement discrepancies between power consumption reported by smart plugs (on the 230V side) and actual LED strip consumption (12V side) are discussed, highlighting the importance of measuring current on the LED side for accurate load assessment. The solution involves dividing the LED strip into manageable sections, each powered by an appropriate amplifier controlled by Fibaro RGBW, ensuring safe operation within current limits.
