Hi there,
Man, I was still sleeping when I replied, I meant which Board, I had forgot about that one… 
but I looked at this 
from the sales page it says’
" * Flexible Power Input
“Supports 12V/2A power via standard DC adapter (EU/US plugs) or direct DC wiring, featuring a universal 5.5mm x 2.1mm DC Barrel Jack connector. Suitable for both temporary and permanent installations…”
and the link you gave is a good, should be AOK…
Just be sure the proper LED strip

Hi alirazi,
So basically, it would work if plug a 12V/3A power to the LED driver. However, as this is not specified in the product’s documentation, there might be some implicit problem if you use the power for which we might not provide further support.
Also, please ensure that the output power should not exceed 24W and that is why we recommend using 12V/2A.
Regards,
John
