The PWM DC Motor Speed Controller with Display is designed to control the speed of a DC motor by adjusting the Pulse-Width-Modulated (PWM) signal. It features a large 0.56-inch 3-digit LED numerical display that provides clear visibility even in challenging conditions. This controller allows you to adjust the duty cycle, which directly affects the speed of the connected DC motor.

Key Features:

• Working Voltage: The controller operates within a wide DC voltage range of 6V to 30V, making it suitable for various applications.
• Rated Current: It is rated for a maximum continuous current of 6A.
• Maximum Current: The controller can handle a maximum current of up to 8A for short bursts.
• Control Power: The control power depends on the voltage and current, enabling you to calculate the maximum power output at different input voltages and current limits.
• PWM Frequency: The controller operates at a PWM frequency of 16KHz, allowing for smooth and efficient motor control.
• Duty Cycle Adjustable: The adjustable duty cycle ranges from 0% to 100%, enabling precise control over the motor speed.
• Display: The large LED numerical display shows the duty cycle (0-100%) rather than the RPM reading. This makes it easy to monitor and adjust the motor speed.
• Compact Size: The controller has a compact form factor with dimensions of 79mm x 42mm x 24mm.

Usage and Notices:

• Motor Compatibility: This speed controller is designed for use with DC motors.
• Polarity Protection: It's important to ensure that the DC input polarity is correctly connected to prevent damage to the controller.
• Motor Direction: The direction of the motor can be changed by swapping the motor wires for forward and reverse operation.
• Potentiometer Adjustment: The potentiometer knob on the controller allows you to change the output duty cycle, thereby adjusting the motor speed.

The PWM DC Motor Speed Controller with Display offers a convenient and efficient way to control the speed of a DC motor using PWM modulation. Its clear LED display and adjustable duty cycle make it suitable for a wide range of applications where precise motor speed control is required.
