The digital potentiometer is a low power device. It can be used to divide a voltage by a known ratio, according to setting, just like the mechanical volume control potentiometer. It is in fact a type of digital to analogue converter (DAC). A DAC usually has greater resolution and different purposes, but can be used the same way.

The digital pot can only be used to adjust a control voltage of a power supply that in turn controls you 0-18A current. This voltage would be used to set the current. How it is done depends completely on the power supply itself. If there is already a current setting knob is is more likely to be achievable.

There are various types of digital pot. Many or most are intended to work with a computer interface such as I2C, a type of serial communications bus. It makes sense to use a simple micro-controller to operate the pot and provide a display. If u need more info about it then visit my link here: led video wall
