Hey, I want to start with my very first WLED project. I simply would like run an LED string at my home-gym around all 4 walls. So basically building a circle close to the rooftop.
I wanted to buy 4x5 Meters WS2815 LED with 60LED/m. This is resulting in a max of 1200 LEDs.
My plan is to divide the circle in 2 potions. One is running clockwise and the other one counter clock wise. So i will end up with 600 LEDs for each of the strings.
I used https://wled-calculator.github.io/ to come up with fuse size and PSU size, but as I am splitting the strings in two pieces I am not 100% if this is correct.
Can somebody please take a look and let me know if this setup is fine?
Also can you recommend a great PSU for this Project.
I thought the MeanWell RSP-200-12 or the MeanWell UHP-200-12 might be a good choice?!
Any MeanWell brand power supply should be good. Your setup looks reasonable. The only thing I would question is if the wires you are using can handle 10 or 16A. If the wires can’t handle the current of the fuse, the fuse is not going to do anything.
TBH I think 5A fuses would be better. 600 WS2815 full brightness RGB-White is under 8A. You are feeding power from 2 ends so that would be 4A per end (likely less than 4A)
One last thing. I would highly recommend using name brand fuses and not whatever cheap ones you find on Amazon, eBay or AliExpress. Often times they do not blow until you have passed close to double the current rating through them. I would stick to Bussmann (Eaton) or LittleFuse (Cooper) fuses. Basically ones you can find at any auto parts store, Walmart….Etc. (Not harbor Freight). I tested some cheap Chinese fuses last week and I was able to send 10A through a 2A fuse before it blew. I don’t remember what the 10A ones took I think it may have been 19A.
Oh I just thought of something - I would make your LED power connections come off the terminals of the controller. Reason: It has a built in relay so that you can cut the power to the LED outputs. Why? Even if LEDs are off (aka black color) They are still drawing power and degrading their circuitry. I would still add the 4 5a fuses to the positive lines or 2 10a per 2 lines. See Pic.
