10A DC motor speed controller with PWM knob

The 10A DC Motor Speed Controller is a compact PWM-based module for precise speed control of DC motors, fans, pumps, and other DC loads. With a simple rotary knob, you can adjust the output duty cycle from 0% to 100%, giving you full control over motor speed without the heat losses associated with resistive speed control. The wide input voltage range makes it compatible with a broad range of 12V and 24V systems.

Key Features:

• PWM speed control via rotary potentiometer knob
• Adjustable duty cycle: 0% to 100%
• Wide input voltage range: DC 6V to 30V
• Maximum continuous current: 10A
• High-efficiency MOSFET switching — minimal heat generation
• PWM frequency: ~13 kHz (inaudible range for most motors)
• LED power indicator
• Compact PCB with screw terminal connections
• Reverse polarity and overcurrent protection (check module variant)

Specifications:

• Input voltage: DC 6V – 30V
• Output current: 10A continuous (15A peak)
• Control method: PWM via potentiometer
• Duty cycle: 0% – 100%
• PWM frequency: ~13 kHz
• Dimensions: ~50 x 30 mm (approx.)

Applications:

• DC motor speed control (12V / 24V motors)
• Fan speed regulation
• Water pump flow control
• LED dimming
• DIY robotics and automation projects
• Solar-powered DC load control
