I'm looking to use 24v LEDs (https://smile.amazon.com/dp/B01LYNJTBN/?coliid=I359TOA9WZGE2V&colid=3HRP4V1TLBJ6P&psc=0&ref_=lv_ov_lig_dp_it) along my fence to help light my pool area. I understand from reading online that I'll want to connect power to the strips at both ends to avoid voltage drop. However, details on how to do that for an electrical novice are sparse, and none discuss how to wire a controller into the setup.
I would like to setup a waterproof 21 amp outdoor power supply at the foot of one corner of the fence. I would then like approximately 65' of LEDs to run from there along my fence to the West daisy chained every ~6' (run A). I would also like a 20' run from the PSU North along my privacy fence daisy chained every ~7' (run B). I planned to give each of these runs their own controller.
My guess is that I'll need to get two DC pigtails to run power from the PSU to the controllers. Then I need a very long piece of (10 awg?) wire to run from the end of run A all the way back to the PSU. What I'm unclear on is:
- Do I connect that wire coming from the end of run A to the same terminals on the PSU that the DC pigtail is connected to or a different set of terminals?
- Where do I connect the positive and negative of that return wire to?
- Will the controller act as a switch and continue to properly function when I'm connecting both ends like this?
- Will connecting run B cause any problem in this setup, assuming it's on its own set of terminals on the PSU?
My alternative is to go with this 120v system that will end up costing me over twice as much: https://www.birddogdistributing.com/rgb-color-changing-led-strip-light-120-volt-high-output-smd-5050-65-feet/
Given the answer provided, I assume that this would be the appropriate way to wire Run A, with Run B a completely separate controller/strip coming off the same PSU:
My understanding is that the amplifier will take the signal from the first strip and use that to control the color and brightness of the second strip. Am I likely to notice anything odd where the end of the first 10m strip meets the beginning of the second, since the second has a fresh 24v power source?
