PWM DC Motor Speed Controller with Mounting Bracket (12-40V 10A)

Description

Product Overview

The PWM DC Motor Speed Controller (12-40V 10A) is a rugged, high-performance speed regulation module designed for precise and efficient control of brushed DC motors. Using advanced Pulse Width Modulation (PWM) technology , this controller provides smooth, stepless speed adjustment from 0% to 100% by varying the duty cycle of the voltage delivered to your motor .

This controller is built for demanding applications, capable of handling a wide input voltage range of 12V to 40V DC and delivering up to 400W of power to your load . It features a robust aluminum mounting bracket for secure and stable installation in control panels, machinery, or custom enclosures, ensuring the module stays firmly in place even in high-vibration environments.

Unlike simple resistive controls, this PWM controller maintains high torque even at low speeds, ensuring your motor doesn’t lose power when you need it most . Built-in protection features, including a replaceable 10A fuse, reverse polarity protection, and over-voltage protection, safeguard both the controller and your equipment from common electrical faults .

This controller is the ideal choice for a vast array of applications, including:

• Conveyor belt speed regulation

• Industrial automation and machinery

• DIY workshop tools (drill presses, lathes)

• Robotics and animatronics

• Electric vehicle prototypes (golf carts, e-bikes)

• Pump and fan speed control

• Laboratory and testing equipment

Key Features

• Wide Input Voltage Range: Accepts DC input from 12V to 40V, making it compatible with a vast range of common power supplies, batteries (12V, 24V, 36V), and industrial DC sources .

• High Power Capacity: Capable of handling loads up to 400W (10A at 40V) . For continuous operation, the rated current is 8A, with a maximum peak current of 10A protected by an onboard fuse .

• Smooth PWM Speed Control: Utilizes high-frequency PWM (13kHz) to provide stepless, vibration-free speed adjustment from 0% to 100% using the onboard potentiometer knob . The high frequency also minimizes audible motor noise.

• High Torque at Low Speeds: Unlike voltage regulators, PWM control maintains excellent motor torque even at the lowest speed settings, ensuring your motor has the power to start and turn loads effectively .

• Integrated Mounting Bracket: Includes a sturdy metal mounting bracket that allows for secure and professional installation onto flat surfaces, panels, or within equipment racks.

• Comprehensive Protection Features:

  • 10A Fuse: A standard, user-replaceable 5x20mm fuse provides overload and short-circuit protection .

  • Reverse Polarity Protection: Safeguards the controller from accidental reverse connection of the power supply .

  • Over-Voltage Protection: Prevents damage from excessive input voltage .

• Low Standby Current: Consumes only 0.02A (20mA) when idle, minimizing power draw when the motor is not running .

• Easy Wiring: Features large, clear screw terminals for secure connections to your power supply and motor. A simple potentiometer knob provides intuitive speed control .

• Rugged Construction: Built with high-quality electronic components and housed in a durable case (approx. 60x55x28mm) , designed for long-term reliability in industrial environments .

• External Control Capability: Includes a 3-pin header for connecting an external potentiometer, allowing you to mount the speed control knob remotely from the main unit for flexible panel design .
