Overview
The High-Power DC Motor Speed Controller is a robust PWM (Pulse Width Modulation) module designed to regulate the speed of 12V–48V DC motors with a maximum current of 20A. Built for demanding applications, this controller supports forward, reverse, and braking functions, making it ideal for electric vehicles, robotics, industrial machinery, and high-torque motor systems.
Featuring efficient heat dissipation (aluminum heatsink), overcurrent protection, and smooth speed adjustment, this module ensures precise motor control while handling heavy loads.
Description
Key Features
✔ Wide Voltage Range – Supports 12V–48V DC motors (20A max). ✔ High Power Handling – Up to 960W (48V × 20A) for heavy-duty applications. ✔ PWM Speed Control – Adjustable speed via potentiometer or external PWM signal (5V–24V). ✔ Forward/Reverse & Braking – Full motor direction control with a simple switch. ✔ Overcurrent Protection – Built-in safety against short circuits and overloads. ✔ Efficient Cooling – Aluminum heatsink for heat dissipation under high loads. ✔ Analog & Digital Control – Compatible with PWM signals (Arduino, Raspberry Pi, etc.). ✔ LED Indicators – Displays power and operational status.
