The 6V-12V 6A DC Motor Speed Controller is a high-efficiency module designed to control the speed of a DC motor using Pulse-Width-Modulated (PWM) voltage. Built around the stable NE555P timer IC, this controller allows you to adjust the duty cycle of the DC output smoothly, providing variable speed control for motors or dimming capabilities for DC LEDs.
The module features a robust design with a dedicated aluminum heatsink to manage heat dissipation during operation. It utilizes screw terminals for secure and easy wiring, making it perfect for DIY electronics projects, robotics, and fan speed regulation.
Key Features:
-
Wide Voltage Range: Operates efficiently between 6V and 12V DC.
-
High Current Capacity: Supports a maximum continuous current of up to 6A.
-
PWM Technology: Controls speed without significantly reducing torque, ensuring smooth motor operation.
-
Heat Dissipation: Equipped with an aluminum heatsink to prevent overheating during prolonged use.
-
Easy Interface: Features a high-quality potentiometer with a knob for precise manual speed adjustment (0% - 100%).
-
Reverse Polarity Protection: Includes protection diodes to safeguard the circuit components.
