None branded ARD-0119 Electronic Components Electronic Hobby Kit

Description: The 40A PWM DC Speed Controller is a high-power motor driver that regulates the speed of DC motors using Pulse Width Modulation (PWM). It accepts input voltages ranging from 9V to 50V DC and can take up to 40A peak current, making it appropriate for motors rated up to 2000W. This module includes a linear potentiometer with an integrated switch for smooth speed control and on/off operation. It's perfect for applications including HHO systems, RC setups, robotics, and electric equipment that require precision motor speed regulation. To guarantee safe functioning, the module has thermal management capabilities and should be kept free of obstructions to allow for proper heat dissipation. For long-term use, keep the current to less than 20A. Specifications: Input Voltage: DC 9–50V. Output Voltage: Linear under load. Maximum Output Current: 40A. Recommended continuous use: 20A (ensure proper heat dissipation). Power Rating: Up to 2000W. 12V → 480W max. 24V → 960W max. 36V → 1440W max. 50V → 2000W max. Speed Regulation Type: Flow regulation. Control Mode: Potentiometer (linear) with switch. Duty Cycle Range: 0–100%. Applications: DC motor speed control, HHO systems, RC setups, robotics, electric tools.
