PWM DC 12V-60V 20A Motor Speed Controller – Digital Display
PWM DC 12V–60V 20A Motor Speed Controller with Digital Display
Take full command of your DC motor projects with this high-power PWM Motor Speed Controller. Designed for a wide voltage range of 12V to 60V and handling up to 20A instantaneous current, this compact regulator gives you precise, smooth control over motor speed — from a full stop all the way to 100% output. The built-in digital display makes it easy to monitor settings at a glance, while the soft-start and soft-stop functions protect your motor and connected equipment from sudden surges.
Whether you're building an automation system, a DIY power tool, a conveyor, a pump controller, or a robotics project, this governor delivers reliable and consistent performance in a compact, easy-to-wire package.
Key Features
- Wide Voltage Range: Compatible with DC 12V–60V power supplies for versatile application across many project types.
- High Power Handling: Continuous current of 10A with a maximum instantaneous peak of 20A — ideal for demanding 775-type and similar high-power motors.
- Full 0–100% Speed Adjustment: Smooth PWM (Pulse Width Modulation) control across the entire speed range.
- Digital Display: Clear onboard readout for quick, accurate speed monitoring and adjustment.
- Slow Start / Slow Stop: Gradual ramp-up and ramp-down functions extend motor life and reduce mechanical stress on connected loads.

Frequently Asked Questions
Q: What types of motors is this PWM DC motor speed controller compatible with?
A: This controller is designed for DC motors operating within the 12V–60V range, including popular 775-type high-power DC motors commonly used in DIY projects, automation, power tools, pumps, and robotics. It is not suitable for AC motors.
Q: What is the difference between continuous current and maximum instantaneous current?
A: The continuous current (10A) is the sustained load the controller can handle during normal operation. The maximum instantaneous current (20A) is the peak it can withstand briefly during motor startup or sudden load spikes. For best longevity, keep your motor's running current within the 10A continuous rating.
Q: What does the slow start / slow stop feature do?
A: The slow start function gradually ramps up motor speed when powered on, reducing electrical and mechanical stress at startup. The slow stop function gently decelerates the motor to a standstill, protecting both the motor and any attached drivetrain components from abrupt stops.
Q: How do I connect this motor speed controller to my circuit?
A: The controller features clearly labeled terminals for the power input (positive and negative), motor output, and any control inputs. Connect your DC power supply within the 12V–60V range to the input terminals, and connect your motor to the output terminals. Adjust the knob or onboard controls to set your desired speed displayed on the digital readout.
