i have read around and finally understood how led strips should be run in parallel for my staircase project. However, i have 1 last question that needed an answer.
According to the diagram, the PSU handles each strip's wattage load separately and the controller does not have to withstand the total wattage load of all the 28m of led strips (400w+).
It's similar to the led strip that i use except that the one i use is 24V instead of 5V.
I will be connecting the power supply to the extra red + black wire via DC connector.
As for the data line, it will be connected via JST connector. Here's the problem though - it seems to supply power as well through the red wire.
So for the data line, do i remove the red wire and connect only two wires (green & black) from the controller to the led strips?
Because if not, to my limited understanding, wouldn't it mean that the controller and the 4th PSU powering the controller have to sufficiently rated to handle the total wattage of the full 28m of led strips since they are all connected?
Thank you in advance :).
