eBay Product Description: Discover unparalleled quality with our brand-new, high-precision PWM DC Motor Speed Controller. Engineered for superior performance, this module is your go-to solution for precise control over your DC motor's speed. It's essential to note that this controller is designed for DC inputs and must not be connected directly to AC sources, such as household 220V AC, to avoid damage. Key Features: Versatile Input Range: With a working voltage range from 4.5V to 35V DC, this controller offers flexibility for various projects and applications. High Power Output: Capable of handling up to 5A of output current, and supporting a maximum output power of 90W, it's equipped to power a wide range of DC motors. Efficient Operation: Thanks to its ultra-low standby quiescent current of only 7uA, it ensures minimal power waste when not actively driving a load. Full Speed Control: Adjust the potentiometer knob to seamlessly change the output duty cycle from 1% to 100%, allowing for complete control over motor speed. High-Frequency PWM: Operates at a PWM frequency of 20kHz, providing smooth and efficient motor speed regulation. Specifications: Condition: Brand new, high-quality product Voltage Compatibility: DC 4.5V-35V Maximum Current: 0-5A Peak Power: Up to 90W PWM Duty Cycle: 1% - 100% Operating Frequency: 20kHz Dimensions: Length: 30mm, Width: 26mm (excluding knob), Height: 14mm Color: As shown in images Package Contents: 1 x PWM DC Motor Speed Controller Module Please Note: Measurement tolerances are normal within a small range.
