Adjustable Speed Control Module,Designed as a compact and efficient adjustable speed control module, it delivers consistent output for DC brushed motors, ensuring reliable speed regulation in applications such as ventilation, cooling fans, conveyors, and automation equipment. High Efficiency Driver Board Design,The controller adopts PWM (Pulse Width Modulation) technology to improve efficiency, reduce power loss, and minimize motor heat generation, thereby extending motor life and enhancing overall performance. Stepless Variable Speed Regulation,Equipped with a high- potentiometer knob, this module provides stepless variable speed control, allowing you to smoothly adjust motor speed from low to high with stable performance and precise speed management. Wide Voltage & High Current Support,This PWM DC motor speed controller supports a broad input voltage range of 12V-40V DC and a maximum output current of 10A, suitable for various DC brushed motors used in fans, pumps, CNC machines, and DIY projects. Overcurrent & Protection Features,Built-in protection design helps reduce the risk of overcurrent and short circuit damage (subject to specific model), contributing to operation for your motor and power supply in long-term use., Manufacturer: Aundhegrtt
