QuinLED dig2analog+ Power Handling
The dig2analog+ is designed towards using lots of boards with a small LED strips connected to each of them. With that said however it’s still quite capable with a max output of 6.3A.
Voltage limits
The board is designed to operate properly with12v – 48v input voltage. The board does no power conversion other then for itself so connected either a 12v – 48v power supply depends on the strip voltage you are going to use!
Voltage in = Voltage out!
Per board figures
The dig2analog+ supports up to 6.3A with a replaceable fuse. It’s recommended not to exceed this fuse value but a lower fuse can be used if more applicable to your setup/situation!
The channels for the dig2analog+ are split in power handling.
The RGB channels can do 3A each
The W1 and W2 channel can do 5A each
Of course while keeping the total power handling of 6.3A in regard.
This gets you very close to being able to run a full 5m/16ft of 28.8w/m strip on a single channel. This would be slightly over the official limits (28.8w x 5m = 144w / 24v = 6Amps) but because of a bit of voltage drop and headroom left should still work quite well and stays under the max limit for the fuse!
If you require even more power per board consider dividing the load over multiple channels or upgrading to a true proper Analog controller that’s designed to handle a bigger load (per channel).
Max power throughput of a single board or chain of boards
A single dig2analog+ board is allowed to transport up to 15A of current into or through the board. These limits are for when board is as at an edge position and receiving the first power input wires or somewhere in between boards in a chain.
As can be seen in the wiring guide I recommend using a Dig-Quad combined with 10A fuses, this would also effectively limit the ingest of a single dig2analog to 10A that it can inject into a chain of boards. If you need more power because of observed voltage drop I suggest using a second output on the Dig-Quad also fused with 10A and connecting that to the point that is furthest away from the first power injection point to equalize power through-out the chain of dig2analog boards up to a maximum of 20A in total.
Auxmer 3-wire 16AWG cable (Easily does up to 10A for a board chain, depending on distance of course)
If even more power is required add power injections to having one in the beginning, one in the middle and one at the end of the chain of boards (however many there are, only the total power figures are important).
This will however not split current equally over all the boards, the middle board will ingest more power then the edge/outside boards of the chain. As suggested above I would not recommend a higher fuse then 10A thus if the middle board draws more then that I suggest re-distributing injection points to have a more equal split such a begin + 1/4th + 3/4th + end points of the chain instead of the middle point.
