Hi!
I really don´t know much more about the inside of the control box. My only goal was to replace the pot that controls the speed with a digital pot. and have the speeds pre-set and controlled by buttons...
I didn´t want to mess with the circuit inside (so far). I wanted a simple ... pot replacement... I already have a circuit with a digital pot that works, but I haven´t finished the code yet to test it with the motor.
I was only wondering if I could not use the digital pot instead... If the digital pot is more efficient and stable, I´ll stick to it... It´s hard to find in my country and it takes 2-3 months to arrive from ebay when I purchase them..
I have measured the 3V between the outer pot connections and the current was tiny(don´t remember the exact value). I could measure it again to have exact numbers of voltage and current.
The control box has an input of 24VDC and 4.8A, and it´s rated for 150W.
Thanks again one more time for helping!
