VCS 2020 Power Distro / Power Injection - Bill Porter

[JoeGagliardi]

Watched this beginning to end and it was great! Thank you Bill, the most concise and easy to follow presentation for non-electrical engineers I've seen!

Electricity almost never been cheap here in Scandinavia.. I look at it this way... A quality power supply with as example PFC will help keep the electricity bill down and I'm not ending up with a cheap power supply that doesn't work after

This didn't age well. It appears that regulated suck (use more power, need more power injection, stops working at a higher voltage) compared to resistor pixels.

I have a 1290 LED pixels and when I followed your formula on power injecting I end up with 6 points to power inject. My question is this, how many injection points can I have in a single run based on this model using 14 AWG low voltage wire? Thank you for you great presentation.

Awesome video. Where can I get the MUYI Connectors mentioned?

Maybe I failed the test but at 39:52 wouldn't 324 pixels at 12v 30% be 324*.055*.3 = 5.346 amps and then 12v*5.346= 64.152 watts not the stated 92W?

For power injection, do you need to run both a positive and negative wire from the power supply to the injection point? Or can you just run a positive line? If you have a negative running through the controller and through all the lights inline in that way wouldn't a negative line for each power injection be redundant and unnecessary?

Great video - about 450 12v pixels running left to right on my house, and now looking at power injection. I have a bunch of 18/3 left which I used to splice strings together. Can I use this for power injection? If not, can speaker wire be used such as CCA? 16? 14?

[GilbertKingAispuro]

So what if you have Strips instead of Pixels?

[frankl]

You are double fusing all your props with the power injection wires. In one of your examples you are sending 15amps to the pixels with a 10A fuse from the power injection and a 5A fuse from the input line.

My comment comes from someone who is starting to learn power injection and this presentation was awesome. I’ve watched so many PI videos you wouldn’t believe it. What has not been answered or at least maybe I’m not seeing is this. The two wires for PI, where do they go? Do they get power from your controller, in my case a Dig-Quad, or do they go on the MeanWell? Sorry for misunderstanding, I’m asking so I don’t cause harm to my equipment. Thanks!
