Hi all.
This is a probably a very simple concept but it doesn't make sense to me. I have been looking for a forum post but cant see one so I must be missing something if I am the only one to be confused.
I am looking into pixel lighting for next Christmas and have never used a controller before. I am looking at the Falcon 16v3.
The question is, if there are 16 outputs, and each output was connected to just a single DC12v 5m LED strip, there would be 16 x 5 = 80 metres of strip. If there are 10 pixels per strip and each pixel uses 0.72W then the power required is 800 x .72 = 576 watts. Even if 2 power supplies are added to the board, and each supply is max 350W, then there is a total of 700W. If we go by the 80% rule for cheap supplies then the power supplied should be no more than 80% x 700 = 560W. So without anything fancy, and powering just 50 pixels per output, we are already over the max suggested power.
This means that power injection (from an additional power supply) is needed directly out of the controller. So what does everyone do? To prevent going over the max power, we would need to supply just the data cable from the controller then power the strips from an external power supply. I know I am going to shake my head when someone tells me what I am missing but please put me out of my misery
Thanks
