High-Power PWM Motor Controller: This DC motor speed controller offers up to 5500W of power and supports a wide current range from 1A to 100A, making it suitable for demanding DC motor applications requiring precise and stable speed control. Wide Voltage Input Range: Designed for versatility, this controller supports 10-55V DC input and can be used with a variety of power supply systems and DC motors. This broad compatibility makes it ideal for DIY projects, industrial equipment, and automation systems. 15kHz PWM Frequency: A 15kHz PWM (Pulse Width Modulation) frequency ensures smooth and efficient motor speed control while reducing noise and improving performance. It helps to finer control motor torque and speed while improving energy efficiency. Motor Forward and Reverse Function: Integrated forward and reverse control allows you to easily change the direction of motor rotation. This is particularly useful for applications requiring bidirectional motion, such as conveyors, power tools, and lifting systems. LED Digital Display: The controller features a clear LED digital display that shows real-time operating status parameters, such as speed level or duty cycle reference values, enabling more intuitive and precise adjustments during operation. Features: Polypotentiometer Speed Control An external potentiometer allows for smooth and precise manual speed adjustment. Users can easily adjust motor speed using a simple knob control, suitable for both beginners and experienced users. Integrated Control Switch A built-in control switch allows for easy start, stop, and direction change without the need for additional modules. This integrated design simplifies wiring and installation and helps save panel space. Durable and Reliable Design The controller uses high-quality electronic components and a robust circuit design, maintaining stable performance even under high load conditions. It is designed to provide users in harsh environments with a long service life an
