Tried to search but couldn't find anything.
I just got into this hobby, so I needed to create an account anyway. I have a 100 foot roofline that will need power injected. Instead of running a power supply near the end I was thing about buying one of These. then running a low voltage wire with my pixels and test the voltage where I'd inject and make it 12v. Thoughts?
Basically adjust the power supply up to 13.5V at the start of the wire, so after the voltage drop from a long run, it would be 12V at the site of injecting.
