5Amp DC PWM Generator Module 4.5V-35V

The 5A PWM Control Module is a compact and efficient speed controller designed for brushed DC motors. Based on high-frequency Pulse Width Modulation (PWM) technology operating at 20 kHz, this board offers precise, stepless speed control from 1% to 100% duty cycle. It's an excellent choice for hobbyists, educators, and professionals working on motor control projects, robotics, and automation systems. Its wide input voltage range and robust 5A output make it suitable for a variety of DC motor applications.

Key Features:

• Wide Input Voltage Range: DC 4.5V – 35V, compatible with common battery packs and power supplies.
• High Current Capacity: Continuous output current up to 5A, supporting motors with up to 90W power rating.
• Onboard Potentiometer: Large rotary dial for easy, manual speed adjustment without external controllers.
• Screw Terminal Connections: Blue terminal blocks for secure, reliable wire connections to power supply and motor.
• Compact Form Factor: Approximately 30 mm × 26 mm × 14 mm (excluding potentiometer), ideal for space-constrained projects.
• Visual Indicators: Built-in components for status monitoring and debugging.
• Stepless Speed Control: PWM duty cycle adjustable from 1% to 100% for smooth, precise motor speed regulation.
• High-Frequency PWM: 20 kHz switching frequency for quiet, efficient motor operation with minimal audible noise.
• Ultra-Low Standby Current: Approximately 7 µA quiescent current for energy-efficient operation.
