Feature: 1. WIDE INPUT VOLTAGE RANGE: Our DC motor controller has an input voltage range of DC12‑80V, making it compatible with a variety of power sources and providing flexibility in usage. 2. HIGH OUTPUT CURRENT RANGE: With an output current range of 0‑30A, our motor controller can effectively drive and control various devices, such as brushed DC motors, LED lights, and brushed DC fans. 3. ACCURATE SPEED CONTROL: Our motor control board allows for accurate speed control of the motor, thanks to the potentiometer adjustment feature. The speed can be adjusted within a range of 0 to 100 percent, with the potentiometer knob also serving as a power switch. 4. PWM MODULATION FOR EFFICIENT CONTROL: Our motor controller utilizes pulse width modulation (PWM) technology for dimming and speed control. This method maximizes energy utilization from the power supply while maintaining high circuit efficiency. 5. VERSATILE APPLICATIONS: In addition to motor control, our controller is also suitable for regulating LED lights and brushed DC fans, providing a versatile solution for various applications.
