The 9–50V 2000W 40A DC Electronic Speeder PWM Motor Speed Controller is a powerful and versatile DC motor speed regulation solution designed for heavy-duty applications that demand high power and precise motor control. It features robust Pulse Width Modulation (PWM) technology to efficiently manage motor speed while minimising heat generation and energy loss.
With its wide operating voltage range (9–50V DC) and high current rating up to 40A, this PWM controller is suitable for a wide variety of DC motor driven systems across industrial, automotive, automation, and DIY project sectors. Whether you’re controlling high-torque motors in electric vehicles, industrial conveyor systems, pumps, robotic platforms, or large fans, this controller delivers smooth, stepless speed adjustment and responsive performance.
The PWM controller modulates the voltage delivered to the motor without dissipating excess energy as heat, resulting in improved efficiency, better torque control, and longer motor life. Its rugged construction is designed to handle demanding electrical loads, and the intuitive design makes integration with existing DC power systems simple.
This controller is ideal for technicians, engineers, and makers looking for high-power DC motor control with precise speed adjustment, robust performance, and broad compatibility with motors operating between 9V and 50V DC.
