I am currently working to power a very large project. I am in the US and am planning to run some large amounts of 5M (16.4') 12V 5050 RGBWW Supernight 300 LED/strip (EBT459). I calculated the length I need to run as 72.5'. My calculations are as such...
The strip I am using uses 3.2 watts per foot, so calculating in with 72.5' gives me a total of 232 watts. Adding in the Rule of 80% it comes out to 290 watts. After calculating amperage, I am at 24.16 amps, so 1- 12v, 30A, 360W power supply.
However, I am running 8 strips, 4 per level, which will require signal amplifiers, set in between each run of 2 strips (10 meters) to combat dimness.
I decided to up the power supplies to be 2- 12V, 60A, 720W power supplies, one to run each length of 4 strips. These will be connected into a TC420 LED timer box then run to the LED strip to control color effects.
My question is, can I run the LED signal amplifier, from the SAME power supply as the strip will be connected to? Meaning, run the leads for the amplifier back to the same power supply that will be connected to the LED controller and have 1 power supply be able to power the entire 72.5' of strip, or will I have to break it down and run multiple power supplies, meaning 1 power supply to run each 2 strip section of LED?
