The output of DC is featured as 12 volts with 5 Amp. Note: These features are reviewed by our experts while reviewing the Power Supply 12V with 2A specifically compatible with Arduino® UNO.

They're 12v so the arduino powers one lead at 5v for the signal, the ground is shared between the 5v and 12v, and finally the LED's are driven by a 12v source separate from the arduino (12v x 2a ...
