I have a 3 dial motor control assembly that is using 3 potentiometers to control 3 independent 110v motors speed.
The label on the pots read TO50K 1339 (first O has a "S" like shape inside). I have not been able to find any spec sheet on this specific pot but in readings with a multimeter I can the following data.
- ~50V depending on pot position
- ~30K Ohms (at max, of course ranges based on pot position)
- 2.5 Watt (based on V*I)
So with all this in mind. Would it be possible to replace the analog pots with digital ICs? I have been trying to match the data with an IC but cannot find anything with the correct voltage or wattage that seems to be required. End of the day, I would want to control the 3 dials with an Arduino board so I can monitor and change motor speed over the internet.
So if anyone has a moment and can help map out a circuit for a single or for 3 pots I would really appreciate the help.
