I'm not even sure why you would want to do this when you could just cut the strip (if needed) and use separate power supplies. Then again, if you wanted to preserve the strip as one piece, I guess I could see it.

you could get oscillations or other undefined behavior if you connect multiple

It's OK to inject power at multiple points along the strip in my opinion, say every 20-30' as long as they share a common ground
Only really necessary to do this if you notice dimness away from a single injection point - there is alot of current being used along the strip between injection points so the PSUs should not 'talk to eachother' or run any risk of reverse current if the output voltages at the terminals are slightly off.
I've used the 5V rails from 2 different computer PSUs to run about 50m of addressable LED strip with injection every 10m. Regular female 2.1mm barrel jacks were soldered to one end of every strip and 2-3 male plugs w/ extension leads were soldered to the PSUs for ease of setup/takedown.

yes it's pretty easy to solder to ends of this LED tape
there are little copper pads and you solder to them

need to come up with another power supply for the remainder of the tape

from another power supply onto the section that has been cut off?

i don't understand the question. There are solder points at both ends of
each
discrete 3-LED circuit. You can splice this tape back together after
cutting
it if you solder carefully.
if you want to use multiple power supplies, they should be connected to
separate sections of LED tape, power supplies' outputs should not be
paralleled
together.

hi Cere,
you're correct that you can cut that type of LED tape along any of the
dotted
lines. It's made up of a bunch of independant circuits which each have
3
LEDs
and resistors and run on 12V, and then they're all in parallel for 12V
down the
whole strip. The current draw from your 12V power supply will change
with the
number of LEDs, but the voltage will always be 12V.

works they way I think it does. My only question, really, is whether I
can
just cut the strip at the designated locations and it will work fine
with a
12v power supply without any need for extra resistors? It looks like
the
LEDs all sit in parallel along the strip so therefore...?
Thanks,
Cere
