I need a digital potentiometer that works on 110 V or 220 V circuits. Is there any type indicated?
In fact, high-powered digital potentiometers are not components, but circuits. There are components that play the role of a digital potentiometer, but operate with low voltages and low currents, changing the resistance at its output in the range indicated by the manufacturer. These components can then be used to control a higher power circuit, with transistors, for example, which will play the role of a higher power pot.
