SUMMARY

The discussion centers on the search for a digital potentiometer suitable for household current (110V, 60Hz AC). Participants clarify that traditional digital potentiometers are designed for low-power applications and are not suitable for high-voltage AC mains. Instead, they suggest alternatives such as variacs for voltage control and triacs or SCRs for dimming applications. The consensus is that digital potentiometers for household current do not exist in the market.

PREREQUISITES
  • Understanding of digital potentiometers and their typical applications.
  • Knowledge of AC mains voltage specifications (110V, 60Hz).
  • Familiarity with variacs and their use in voltage control.
  • Basic concepts of dimming circuits using triacs and SCRs.
NEXT STEPS
  • Research variacs and their specifications for controlling AC voltage.
  • Learn about triacs and SCRs for implementing dimming solutions.
  • Explore the limitations and applications of digital potentiometers in electronic circuits.
  • Investigate alternative devices for household current control beyond digital potentiometers.
USEFUL FOR

Electronics enthusiasts, electrical engineers, and anyone interested in controlling household current or exploring alternatives to digital potentiometers for AC applications.

Has anyone here ever heard of a digital potentiometer that is built for household current? I'm talking about US power supply (110v 60Hz AC). I've been looking for one to buy. I tried searching online to look for prices, only to find that they don't seem to exist.

Any links to an online store, or information about the existence or non-exitance of such a device would be greatly appreciated.

Not sure what you mean by a digital potentiometer for the AC Mains. I've not seen a use for a potentiometer on the AC Mains. Are you thinking more of a variac, to get stepped-down versions of the AC Mains voltage? Or are you looking to dim something like a light? If dimming, you don't use a potentiometer. You use triacs or SCRs to make dimmers:
