- Easy to use control knob: An intuitive knob lets you adjust speed quickly. Rotate clockwise to increase, or counterclockwise to decrease, for straightforward operation. - Precise speed settings: The built in potentiometer provides accurate, repeatable speed control without external signals, delivering consistent performance for engine applications. - Analog signal compatibility: Can accept analog control signals from 0-5V by properly connecting the potentiometer cable, expanding suitability for pumps, fans and similar tasks. - Wide voltage range and current: Operates on 7-24V and supports up to 15A, making it suitable for compressors and water pumps. Use scenarios - Industrial pumps and fans in automation that require smooth, reliable speed control within a 7-24V system. - Small compressors or water pumps that need adjustable speed and solid current handling. - Prototyping or automation projects where a 0-5V control signal from a PLC or controller sets speed.
