David, nice addition to your line of lighting products. It was wise that you informed the viewers about removing the data line, and, when a second power supply unit is used, to remove the power from the inline plug.
Question. So if you had a meanwell 12v 350 watt power supply how many power injections can you do off of 1? I'm new to this and just started making props and building controller boxes and getting things together for a light show christmas 2023. I know distance makes a difference as I'd rather run a separate power supply 50 ft down than run 50ft of wire. But either I missed it or I'm confused as to how many power injections you can run off 1 or how you can calculate that?
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?
If I'm Power injecting from a 2nd supply for the same string with multiple PI points, do i need to cut the V+ from all the tees? Or is the first cut on the first PI point good enough.
If I power inject at the very end, from a different power supply that my controller is plugged into, how would I do it. In the video you take out a pin, but if I have item #723F I plug the positive and negative into the supply? Can you run me through what I need to do exactly.
This is exactly why we do not provide advice on power injection. Power injection is like putting a turbo on your car - done right it is all good, done wrong you can burn your house down. Stick with long range, save and much easier.
Do you actually have to remove the pin? If the SPI output you're using doesn't have any data going down it, then it wouldn't cause any interference, right?
Yes, IF there were not any data wire down that cable but 100% of our cables have data. Not removing the data cable could result in reflections in the cable.
Honestly, I find these power injection Tees very expensive and a bit redundant. To power inject, one will need to bring the power through some wires, why not simply slice pixel wires and add a two pin connector (male & female) on both pixel and power wires and connect them up. This is what I have been doing for over three years of using 5v pixels only in my display.

Thanks for this useful information, now i get how the power injection works.....

Not sure, depends on the number of pixels and your layout. See: www.holidaycoro.com/kb_results.asp?ID=173
Question, stead of removing the positive pin from the PI cable when using a 2nd PSU, can I only connect the ground wire at the disto. board?
Power injection is 100% custom for each customer's setup and thus it will require each customer to complete a unique design.

I’m confused on how to actually inject the power, how do I connect the tee to my power supply I don’t know all that wiring stuff

@@HolidayCorowhat is meant by long range?

Yes, IF there were not any data wire down that cable but 100% of our cables have data. Not removing the data cable could result in reflections in the cable.
Is the pin removal a permanent modification? Or can the pin be re-attached later?
The modification is permanent.
Permanent.
As always, very useful information. Thank you!

Customers use many different options and there are pro's and con's to each method. This method is waterproof and easily disconnected and connected.
