To answer your question about where to inject it does not matter if it is at the end of 200 or on the middle. The voltage flow either way.sck1ng said:I got 4 trees done from yesterday to today.. Have four more to go. Have to figure in power injection also as 200px is too many. Should I inject at the end of the 200 or in the middle between px 100 and px 101?
For what it is worth....
Just wired up 3 of my 24 mini trees, 50 x 5V pixels each the same as yours.
they have 3m of 0.5mm 4 core security cable on each one. Buck converter at the base as per Plasmadrive's drawing.
Test with ALL WHITE ON.
24V supply output = 24.5V
End of 1st string of 50 pixels = 23.8V
End of 2nd string of 50 pixels = 23.4V
End of 3rd string of 50 pixels = 22.9V
As the voltage can drop to 12V to the Buck Converter and still give 5V I don't see a problem with going to the max of the first cable but I intend to put 4 sets of 6 trees on a Pixlite 4.
