Description:
The 12V-40V 10A PWM DC Motor Speed Controller with Knob is a high-performance DC motor speed control module designed for smooth, efficient, and precise motor speed regulation. Supporting an input voltage of 12V-40V DC, it delivers up to 400W output power with 10A peak current (8A continuous). The built-in PWM (Pulse Width Modulation) technology operates at a 13 kHz frequency, providing stable performance, high torque, low heat generation, and energy-efficient operation. With an adjustable 10%-100% duty cycle, users can easily control motor speed using the onboard rotary knob. Ideal for DC motors, cooling fans, water pumps, robotics, automation systems, electric vehicles, Arduino projects, and DIY electronics applications.
