I have read as many threads on this site and others related to this, but haven't found any that specifically answers my questions.

I have about 20 WS2811 LED Strands. They are 12V and each LED uses about 0.6 watts so 600 watts for the entire 1000.

So, that would mean 600W at 12V is 50amps. However, many people say you need to apply power every so often due to voltage drop.

But is it really as simple as attaching them end to end with a power supply that is 12V at greater than 50 amps? If I want to apply power to multiple entry points along the massive strand, how do I split off the power from the supply to each point?

If I used a power supply like this one

Does each split to supply power need to come from another one of the V+?

Is there a better way to connect all these strands together?

  • \$\begingroup\$ You can put multiple wires onto each power supply terminal or run a single positive and a single negative wire that goes the length of the strips connecting to them every few meters. \$\endgroup\$ May 26, 2022 at 14:55
  • \$\begingroup\$ For a 50 A total load, I would split the load into three parts so I could use all three pairs of output terminals on the supply. \$\endgroup\$ May 26, 2022 at 16:04
  • \$\begingroup\$ So with a power supply, if you use all three parts, does the current split 3 ways as well? Or does each still receive the full load of say 50amps? \$\endgroup\$ May 26, 2022 at 16:47
