1. Easy installation and operation: Thanks to the screw terminals, users can easily install the 12V speed controller. The motor speed controller also comes with an adjustable start/stop switch and a speed control potentiometer for effortless handling. Whether for 12V DC motors or other applications, this regulator provides a userfriendly solution. 2. quality material for durability: The PWM DC motor speed controller is made of PCB material, ensuring durability and wear resistance. This construction guarantees a longer service life for the digital display DC motor controller, making it ideal for various applications, including switchon motors and electric motors. 3. Precise speed control: The PWM controller enables continuous speed adjustment from 0% to 100%. The digital display shows the actual speed percentage relative to the maximum speed, allowing precise control of the switchon motor. This feature is particularly useful for speed controllers and stepper motor control. 4. Wide input voltage range: With an input voltage range from DC 6V to DC 60V, this PWM motor controller is versatile and compatible with various power supplies, including 12V, 24V, 36V, and 48V.
