LED striplight DMX controller wiring question

elated to another thread I recently posted, I've figured out what equipment we will be using. Not 100% sure on how to hook it up it's a single color LED strip.

LED strip has 2 wires, red and black. Controller is going to be a Chinly 24 channel. Controller outputs are set up for RGB so V+, R,G,B. Controller has 8 outputs like that.

I'd like the channel numbers to be consecutive if possible(using 4 or 5 separate strips). To do so it seems like I'd just hook V+ and R, to the first one, V+ and G, to the second and so on. That would result in 3 strips sharing a V+. Not sure if that is an OK thing

The other option would be to connect the strips to the V+ and R of different groups. The result would be the channel numbers being 3 apart(i.e. 121, 124, ect). I'm aware I could soft patch the board but I try to avoid making those changes in this space.

There shouldn't be any trouble connecting them to the RGB channels. You'll just have to be very careful with your math so as to not overload that channel.

The led strips should have 4 wires (if the strips are RGB)

Be aware that that controller needs a separate power supply

Light change of plan but I think I've got everything I'm going to need ordered.

Had to go with a pair of 3ch 30amp(3x10amp) controllers, and matching 12v 30amp power supplies. The led strips that were ordered are single color that draw 12v 6amps per 5m. Max length for a step is 24' for I'm figuring that's going to draw about 9amps. The controllers are rated to 12-24v. LED's are 12v and I wasn't sure on if the controller would regulate the power to 12v if I used a 24v supply so I went with the 12v, even though if I had, the descriptions seem to indicate I could use a smaller power supply.

I'm looking to build some sort of plexiglass enclosure(with a 140mm fan for ventilation) to house the controller/power supply as they have exposed terminal strips.

Your maths sounds good. Beware of losses and other factors that may increase your current.
in these units voltage in = voltage out. So you were correct in selecting 12v power supply for your kit. I use 16.2v batteries on 12v strips and they cope with that but I am not sure how much more before the smoke might escape
