Signal Chain for Connecting the Color Tunable LED Strips


I'm working to integrate about 128 linear feet of the color tunable strips into an upcoming installation. We would ideally be controlling dimming and color via DMX, but I'm not sure I'm quite fully understanding the signal chain for connecting these, and how best to actually wire them so they act as a single unit. 

As a starting point, it might be helpful to know that the FilmGrade™ HYBRID LED Strip Lights have a max run of 32.8 feet. Due to this, any connected lengths that exceed that length will encounter voltage drop and decreased light output. 

As a further consideration, our 24V power supplies have a maximum output of 96W in accordance with class 2 ratings. As each foot of the Hybrid LED Strip Lights requires 45W per reel, roughly two full 16.4 ft reels can be connected to a single power supply. 

As can be noted within the user manual for the DMX Dimmer and Decoder product, multiple units can be daisy chained together. When they have been connected, the downstream units will emulate the settings of the primary upstream DMX Dimmer and Decoder. 

So I could use a single power supply and a single DMX unit per ~32 feet of tape, and have them all talk to each other. Correct?

I think this makes sense. Are the products I sent earlier the correct ones?

We can confirm that so long as each ~32-foot length has a dedicated DMX Dimmer and Decoder as well as a dedicated power supply, the installation should allow for daisy-chained operation. 

If any of the LED Strip Lights of DMX Dimmer and Decoder units wind up being unneeded for your installation, please feel free to take advantage of our 30-day return policy. 

So long as the LED Strip Lights are in their original condition and have not been cut or altered, including the adhesive backing being removed, we will gladly provide you with a prepaid return label. 

As the FilmGrade™ HYBRID LED Strip Lights requires a 24V power supply, we would recommend the matching voltage 24V FilmGrade™ DC Power Supply for LED Strip (PN3092). Further, as the power supply uses a barrel-jack adapter, your installation may benefit from utilizing the Female DC Barrel Jack Plug Adapter (PN7094) and extra wiring for connection to the DMX Dimmer and Decoder power contact pads.
