power injection

    Help needed for Noob.

    Hey, New to the hobby, I've always just used dumb LEDs, but the guy up the road whom I have unofficially always competed with has now gone this route, so now I need too in order to be better. (yeah, I'm that kind of guy). So, I'm starting in January 2024 to have everything ready for Christmas...

    Wire gauge concerns with multiple 600W PSUs

    Hi, I am setting up my first show and really don't want to burn the new house down... My main question is whether I can power inject with 18 gauge wire? If so, do I need to change my approach to power injection? The pixel voltage calculator indicated no issue with voltage drop in each power...

    Can I get away with no power injection, if running 5V strip at 50%?

    Hi all, I'm still very new to this, and I'm thinking of adding a 10m long straight run on my front porch. I'm thinking of going with two 5m strips of 5V WS2812 or WS2811 at 30 pixels/m. http://spikerlights.com/calcpower.aspx is showing me green if I run the lights at 50% (attached). Is this...

    Answered Problem with Power Injection

    I'm having some troubles with the power injection for my mini trees. I have 8 mini trees which are broken into two lots of four. Each mini tree plus star uses 200 5v pixels (4 x 50 node strings). The wire diagram below shows how I have them wired up (I have only showed one group of four...

    Another PI Thread

    Every time I think I've got a decent understanding on handling power injection, I get some doubts, investigate that and return to square one and I'm confused once more. Watching @lithgowlights present at the ACL mini in 2017 Here he suggests not to cut the +V as you will then have two pixels...

    Basic setup diagram, with power injection example

    Hey ACL team I'm finding that even reading through various material (inc the 101 Manual), posts, watching videos, etc. that I'm not yet sure I have a handle on some of the basics. This diagram is what I think I understand so far, so I'm looking for some validation here. My diagram depicts a...

    12V Strip max length without power injection

    hi all, am I right that strips which support 12v or 24V have fewer addressable pixels? so 5V, 60smd/m = 60 pixels 12V, 60cmd/m = 20 pixels 24V.. ? I need to do an installation with multiple strips of 6,2m length. Will this work with 12V strips If I inject at the beginning and at the end of...

    Answered Problems with double or superior led strings .....

    guys, I have a problem with the LEDs ... if I combine two strings of 50 pixels one and go into the test with F4V3 the first turns on properly, while the second no! I open a new package of 10 new LED strings and I tried to repeat the same operation, with the difference that joining two strings...

    Question about when to have a 'common ground'

    Hi all, I'm planning on putting in more than one power supply in my show this year, and want to make sure I understand the need for a common ground between those power supplies. If each power supply is powering different, disconnected elements, do they need a common ground between the other...

    48 VDC to 5 VDC with converters and quicksplicers?

    hi all, I plan to run a 48V line from my meanwell HEP-320-48A along my 30m 5V led stripe and I do power injection every 2m. (it needs to be 2m) I want to use DCDC converters to get the voltage down to 5V. 2m of my stripe need 36W and 7,1A. I found cheap converters on alibaba: 48 VDC to 5 VDC...

    Presented by lithgowlights. What happens to your RGB Pixels if you don't inject power and what are the common methods of power injection with one or multiple power supplies?

    Power Injection Question

    in the picture is there a necessity to have the power feeding between the two strings of pixels? Assuming: controller output is 5VDC at 5A (25W) and each string of 50 pixels draws 15W; only two strings of 50 pixels. As per this wiring diagram? -V ---P---P--- V- D ---P---P +V ---P---P---...
