QuinLED-dig2analog Power Handling
The dig2analog is designed towards using lots of boards with a smal LED strips connected to each of them. With that said however it’s still quite capable with a max output of 3A by default and upgradable to 6A by the end user (read more about that in this article here).
The board is designed to operate properly with either 12v or 24v input voltage. The board does no power conversion other then for itself so connected either a 12v or 24v power source depending on the strip voltage you are going to use!
Per board figures
Default figures (3A limit)
When adhering to the 3A limit this can be seen as both the board limit and each individual MOSFET limit at the same time. Since there is no configurable PWM rate (it’s locked to 2kHz) anything up to 3A (72w with 24v LED strip!) will be fine for the board or an individual MOSFET.
This 3A total configuration is more the enough to even run 5m/16ft of RGBW COB LED strip. Only when you want to run high power 28.8w per meter CRI95 white LED strip you might start running into some limits. If so consider either upgrading the board to 6A (see here) and dividing the load over multiple channels or upgrading to a true proper Analog controller that’s designed to handle a bigger load (per channel).
Optional 6A limit mode
When you upgrade the board with a second PTC (Auto-reset fuse) the limits change a little bit. The overall limit of the board is raised to 6A but I’d still advise to keep the individual MOSFETs limited to about 3A to not have them overheat.
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.
If even more power is required again split all the 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.
