What size of power supply is suggested to run three strips in parallel continuously? 20A? 30A?

Total power consumpion of LED strip is 75W, so 10A 12V DC Power supply is more than enough!

We need to work our math out a bit better here. While 225 watts divided by 12 does equal 18.75 amps. That is on the transformer only. In reality, it is drawing 1.875 amps on a 120 volt circuit breaker. Not taking into account volt drops, transformer draws and voltage availability; but lets call it 2 amps. So no need to place on 20 amp circuit if not available.

I believe they are rated at 75 watts x 3 units equals 225 watts divided by 12 volts equals 18.75 amps. Therefore a 20A [power supply will work.

There were absolutely no directions at all with the lights. Sorry! My electrician did not tell me the 20A or 30A.

I ordered this Power supply from amazon to power my led strips. ..JACKYLED DC 12V 2A 2.0A Switching Power Supply Adapter For 110V- 240V AC 50/60Hz and it works just fine.

Each strip requires 12VDC at 6amps. Do not daisy chain all 4 strips together. The strips can't handle 24 amps through the traces of 4 strips. You need to connect each strip separately to the power supply. You can use 4 separate 6amp power supplies or use one 30amp power supply. The data connectors need to be daisy chained together. You input the data to the first strip and it passes to the rest of the strips. The RGB LED's are in groups of 3 so 10 pixels per meter or 50 pixels per strip. 4 strips equals 200 pixels total. I hope this helps.

There is a connector on the other end to allow multiple strips to connect. However the power supply and driver module will limit the number you can connect. Two shouldn't be a problem, but not more than three.

You can't run them in series. Parallel only. Run a set of wires from the power source to the start of each strip. Incidentally, a couple things about that power supply...It's not as pictured (at least in my case) It has a noisy fan. I returned it and used a re-purposed computer power supply. Also, this power supply will not run 4 strips. If I remember correctly these strips run 72 watts each which is about 6A at 12 volts. 6X4 = 24A required. And with the distances you are talking about, you're going to need a bit more than minimum.

It depends on the maximum amperage of the controller. I'm assuming you meant 12V, 120W. This would be a 10A power supply. If your controller can handle 10A than you do not need a repeater. If your controller can't handle 10As, than you will not only need a repeater, but a separate power supply for the controller and the repeater. Keep in mind also that each 5M strip is supposed to be able to pull 6A's if you ignore voltage drop. They usually pull about 5A because of voltage drop. This means that if you put these two LED strips on full blast (white), you will be maxing out your power supply even if your controller can handle 10As. This is generally a bad idea; it always a good idea to have some overhead.

According to the product package one power supply can handle up to 36 watts and each LED strip is only 3 watts so you should be able to connect 12 in sequence without any problems.

I have connected one 12 volt 3 meter strip to a 30 amp 12 volt power supply and tested the amp draw to come up with these values. LED Power draw information - - 3 meter set - - 1 - Green only = 1.4 amps @ 12 volts 2 - Red only = 1.39 amps @ 12 volts 3 - Blue only = 1.19 amps @ 12 volts 1+2 - light green = 2.5 amps @ 12 volts 1+3 - light blue = 2.27 amps @ 12 volts 2+3 - purple = 2.28 amps @ 12 volts 1+2+3 - white = 3.18 amps @ 12 volts 3.281 feet in one meter Hope this helps.

I have ganged two of these 30A supplies together in parallel to provide 60A. I did this using two high-current diodes to prevent one supply from pushing current into the other (because the two supplies will have slightly different voltage settings. You can up regulate the voltage settings on the supplies to offset the 0.6V drop across the diodes. This works fine for me; I usually draw a total of about 55 amps from the pair, but in initial testing they did produce 60 amps. I did not run them at 60Amps for very long however. Garrett Odell

I measured 1.25amps for one 5m string of cool whites at 12 volts, so you might just be able to run 2 strings off a 30w supply as that would be 2.5amps. Might need to watch the temperature of the power supply. I opted for a 5amp/60w supply to run 2 strips in my attic installation (since it can get quite hot up there), and if needed I could add a 3rd strip w/o issue with that supply. Not that much more expensive for a few extra amps of supply.

You can't have 2 strips coming into the same adapter; not as far as I know without doing some wiring. I could be wrong tho :) However, the adapter is plenty powerful enough to run both your strips. I believe its made to power a little over a 16' strip of LEDs. I used one on a bookcase and it was fine. The only thing I had to do though, was cut the LED strip when I got to the corners and use a special connector you can buy on Amazon too, but I didnt have to worry about going an opposite direction like you are. I would say you'll maybe have to solder the wires or the strip together close to the outlet.

You can put up to 2 (maybe3) together depending on the power supply you are using. After that you must use a small amplifier for each of 2 more strips.

I think you will need to have a repeater of some sort. I remember reading somewhere that you can only have two strips connected to one power supply. I also don't know how your power supply holds up so I wouldn't suggest more than two, One of my power supply starts to burn up after a while and it is only connected to one strip so the quality of the power supply is questionable.

Thanks for your question. Three strips @ 60 watts equals 180 watts. The three hundred watt transformer would the transformer you needed.

Yes, just add a 12 volt power supply, there should be a power connecter at the beginning of each strip.

You have to add amount of watt of each strip and not exceed 80 watt. If your strip is 10 watt, you can use 100 watt power supply for 8 or even 9 strips.

Yes ... I used this power supply to power (3) strips with a signal booster placed inline with the three strips.
