Professional-grade 100 watt rheostats and adjustable resistors designed for precise industrial automation and process control. These motorized rheostats combine high-precision proportional controls with reliable AC/DC motors, offering variable resistance settings from 1-15 RPM with slip clutch protection for enhanced durability.




When sizing a rheostat, wattage rating is a primary consideration. On Line Controls offers rheostats in 25, 50, and 100 watt configurations to match various power requirements. For demanding industrial automation and process control applications, a 100 watt rheostat provides the capacity needed for reliable, long-term operation. You should match the wattage rating to the maximum power the rheostat will need to dissipate in your specific application.
