DC Motor Speed Controller – Compact and Precise Power Control for Small Motors and Fans Key Features and Benefits: • Wide Low Voltage Control: Operates on a DC input range of 1.8V to 15V, allowing compatibility with a variety of lowvoltage systems. Adjustable PWM duty cycle from 0 to 100 percent provides smooth and efficient speed regulation without the need for powerwasting resistors. This ensures precise control for small DC motors and cooling fans, ideal when accurate speed settings are required. • Output Capability: Rated for up to 2A current with a maximum power output of 30W. Suitable for driving common micro DC motors reliably, delivering consistent performance for hobby projects, repairs, and smallscale automation tasks. • Builtin Safety Protection: Features an integrated selfresetting fuse and additional protection measures to reduce the risk of damage from overloads or wiring errors. This increases product reliability and helps prevent costly failures during operation. • Convenient Installation and Use: Includes an onboard power switch for quick on/off control and an LED indicator for immediate visual status confirmation. Simplifies setup, bench testing, and daily operation without the need for extra components. Practical Applications: 1. Controlling speed of small cooling fans in electronics projects or work where precise airflow is required. 2. Regulating micro DC motors in DIY robotics, providing smooth acceleration or deceleration for controlled movement. 3. Adjusting speed for miniature pumps or mechanical assemblies in model building and prototyping where consistent performance is important.
