AC Motorized Potentiometer 115V Industrial Grade

AC motorized potentiometers designed for industrial use typically include a circuit board with mounted starting capacitor, dynamic braking diode, and solder terminals for straightforward wiring connections. Some models also include snap action switches at each end of travel. For exact wiring guidance specific to your model, it is recommended to consult the product specifications or contact On Line Controls' technical support team directly.

An AC motorized potentiometer is a precision proportional control device that combines a high-precision potentiometer element with a reversible AC motor — in this case, a 115V AC motor — to automate the adjustment of analog-driven devices. It provides variable resistance control and is engineered for smooth, reliable operation over long periods in industrial automation applications. Available in wirewound and conductive plastic element types, these units also incorporate slip clutch protection to prevent damage during automated or manual operation.

AC motorized potentiometers are available in a wide range of power ratings from 0.5W up to 100W. Specific options include 0.5W, 1W, 2W, and 5W for potentiometer models, and 25W, 50W, and 100W for heavy-duty motorized rheostat applications requiring high wattage control.

The slip clutch serves two key functions: it protects the potentiometer end stops from damage when the motor reaches the limit of travel during automated operation, and it allows for manual adjustment of the potentiometer without requiring the motor to be disengaged. This feature is essential for preventing motor overload and extending the overall service life of the unit.

Wirewound elements offer high power handling capacity and precision, with a life expectancy of up to 1–2 million turns, making them well-suited for high-wattage and high-resolution applications. Conductive plastic elements provide significantly longer operational life — up to 50 million turns — along with essentially infinite resolution, lower inductance, and smoother performance, making them ideal for demanding applications where longevity and precision are critical.

These industrial-grade 115V AC motorized potentiometers are used across a broad range of industries, including industrial automation (controlling automated machinery and manufacturing systems), process control (regulating flow, pressure, and speed in chemical and material processing), medical equipment (providing precise analog adjustments in clinical devices), and energy and power (managing high-wattage systems in power plants and electrical distribution facilities).

Yes, dual gang motorized potentiometer configurations are available for feedback systems. These models feature high precision wirewound elements with high resolution and linearity, and are offered in matched resistance pairs such as 1K/1K, 2K/2K, 3K/3K, 5K/5K, 5K/10K, and 10K/10K. They include slip clutch protection and are available in both single-turn and 10-turn configurations.
