Hopefully simple question: I am planning 6x RGBW COB strips about 3m each, separated by about 2 feet so like total 6m wire. The strips I am using are rated 75w max (for 5m) so my 18m should consume about 270 watts at 24v = 11.25A output. Is it safe to use a 15 A fuse in a Quinled-Dig-Uno? I see they are rated for 15A continuous and this is only slightly over the 10A stock. Also gives 33% margin, so thinking should be ok.
Also, concerning wire size - I was planning to use 16AWG wire for the wire run. Not sure this is enough? Getting mixed results from available calculators. Total wire run as I mentioned is about 6m to the furthest segment (each are wired in parallel), and total current max is 11.25A. Thoughts?
The LED’s can use that much power, but the strip they are made from generally can not handle that much power. You would need power injection for you to use 10A of power, thus the reason the big fancy controllers (Falcon, Kulp, Genius…) all use 5A fuses per port.
Yes I realize that - since they are all in parallel, each would take only 2A or so, not the full 11. I was more concerned about the Quinled traces being ok with the full 11A all the time.
Quindor recommends no more than 10A fuses with a total load of 30A. If you scroll down to Power Handling @Quindor gives lots of info about power usage.
You could also run a second power line to another fuse. That would split your draw per fuse in 1/2
