DC Motor Speed Controller 5V-35V 5A PWM

DC Motor Speed Controller (5V-35V 5A PWM Switch Module) is a compact, high-efficiency Pulse Width Modulation (PWM) speed regulator designed to control the speed of DC motors, brightness of LED strips, and output of DC heating elements without sacrificing torque or power efficiency. Operating across a wide voltage range of 5V to 35V DC, it handles up to 5A continuous output current (90W peak output power). Featuring an integrated multi-turn potentiometer knob with an onboard power switch, self-recovery safety fuse, and power status LED, it provides smooth, linear speed control from 1% to 100% duty cycle for industrial automation, DIY power tools, and robotics applications.

Features

• Wide DC operating voltage range (5V to 35V DC), compatible with 6V, 12V, and 24V DC systems
• Advanced High-Frequency PWM control providing smooth 1% to 100% speed regulation without motor hum or torque loss
• Integrated power control knob with an ON/OFF switch function for immediate power isolation
• Onboard self-recovery resettable fuse protecting connected loads and power supplies against short circuits and overcurrent spikes
• Supports continuous output current up to 5A (up to 90W total output power)
• Compact PCB layout with heavy-duty screw terminals for easy wire termination without soldering
• Dual status LED indicators providing visual feedback for power and output drive activity
• Multi-purpose application suitable for DC motors, HHO generators, DC fan speed regulation, and dimmable LED lights

Applications

• Speed control for 6V, 12V, and 24V brushed DC motors, electric drills, and mini actuators
• Dimming high-power 12V/24V DC LED strips, halogen lamps, and backlight panels
• Speed regulation for DC cooling fans, ventilation exhaust units, and aquarium air pumps
• Temperature tuning for low-voltage DC heating elements and soldering wire warmers
• Polytechnic diploma, university engineering thesis, and industrial automation control projects

Important Notes:

• DC Power Input Only: This module is strictly designed for DC power supplies (e.g., 12V batteries, DC power adapters). Do NOT connect it directly to 220V AC household mains power; doing so will cause immediate destruction and hazardous failure.
• Input Polarity Care: Ensure correct input voltage polarity (Power In + and Power In -). Reverse power connections can damage the internal switching MOSFETs despite onboard fuse protection.
• Not an H-Bridge Driver: This is a uni-directional PWM speed controller, not a bi-directional H-Bridge motor driver. It regulates speed in one rotation direction; it does not reverse motor direction.
• Thermal Dissipation: When operating continuously at loads above 3A or near 90W power output, ensure adequate enclosure ventilation to prevent thermal buildup on the switching MOSFET.

• 1 x DC Motor Speed Controller 5V-35V 5A PWM Module (with Nut & Washer for Potentiometer mounting)
