60 Watt Power Rheostats for High Load Industrial Systems

A resistor provides a fixed resistance value in a circuit, while a rheostat is a variable resistor that allows resistance to be adjusted during operation. The motorized rheostats featured here are wirewound rheostats with a combined motor-rheostat design, enabling high-precision proportional control for industrial automation — something a standard fixed resistor cannot provide.

Both AC reversible motors (115 VAC) and DC motors (12 VDC) are available, allowing you to select the motor type that best fits your specific application needs.

Slip clutch protection prevents damage to the rheostat's end stops and ensures reliable long-term operation under varying load conditions, making it a critical safety and durability feature in demanding industrial environments.

AC motors offer 1–15 RPM options, while DC motors typically provide 1–2 RPM, giving engineers precise speed control suited to different proportional control applications.

Yes, CE compliant models are available, making them suitable for international shipping and use in global industrial applications.

These motorized rheostats are used across industrial automation (automated manufacturing lines and robotic systems), process control (chemical and pharmaceutical facilities), and equipment manufacturing (industrial control equipment requiring variable resistance adjustments).

All motorized rheostats come with a standard 3-year warranty on parts and labor, along with unlimited technical phone support. They are designed and manufactured in Massachusetts by On Line Controls, Inc., a company with over 44 years of manufacturing excellence.
