Features Adjustable Speed Control: One of the primary features of a PWM controller is its ability to adjust the motor speed. This adjustability is particularly beneficial in applications like conveyors, fans, or pumps where speed control is necessary to optimize performance and energy consumption. Protection Features: The PWM controller uses screw terminals for quick and easy wiring and is equipped with a momentary start/stop switch and a speed control potentiometer. Versatility and Integration: PWM controllers are compatible with a wide range of DC motors and can be easily integrated into various electronic control systems. This versatility makes PWM controllers a popular choice among hobbyists, researchers, and industrial applications where precise motor control is needed. Efficiency and Energy Saving: PWM controllers are known for their efficiency. By switching the power to the motor on and off rapidly, a PWM controller minimizes power loss in the speed control process. Easy to Read: Designed with a digital display that shows the rate in percentage of actual speed to maximum speed. Spec: Features: Speed controller is made with high quality circuit board which ensures a longer service life. This simple and easy-to-use DC motor speed controller has an stable performance. Designed with a digital display that shows the rate in percentage of actual speed to maximum speed. This motor speed controller uses screw terminals for convenient and quick wiring. Comes with a momentary start/stop switch and a speed control potentiometer. Specifications: Output Voltage: Linear with load Output Current: 30A Continuous Current: 20A Speed Range: 0% to 100% Regulation Method: Potentiometer Regulation Type: Regulating Current Control Frequency: 15KHz Wiring Type: Screw terminal Package Includes: 1 x Speed Controller Note: 1. Please allow small size error due to manual measurement. Thanks for your understanding. 2. The digital tube only displays 0-100 motor full speed percentage, not the actual motor speed. For example, if the maximum motor speed is 500 rpm, it will display 100 at 500 rpm and 50 at 250 rpm. Package List
