RV20N Speed Control Variable Potentiometer

Description:

The RV20N Speed Control Variable Potentiometer is used in motor speed control systems and variable frequency drive circuits for manual adjustment of analog control signals. Commonly installed in VFD panels, DC motor controllers, conveyor systems, fan control systems, and industrial automation equipment requiring adjustable speed reference inputs. Maintenance teams and system integrators use this potentiometer for replacement, retrofit, expansion, or repair of industrial motor control and operator interface systems.

Applications:

The RV20N potentiometer is commonly used in variable frequency drives, DC motor speed controllers, HVAC systems, industrial fans, conveyors, mixers, and process equipment where operators require manual adjustment of motor speed or process variables. The panel-mounted design makes it suitable for control panels and machine operator stations requiring reliable analog input adjustment.
