Features Adjustable speed and direction: come with high current and large torsion, support CW and CCW, you can adjust the speed and direction of rotation of the motor. LINEAR SPEED CONTROL The speed control type is current control, the speed control method uses potentiometer (linear), and the duty cycle range of the speed control is 0-100%. Excellent PCB: use high-quality PCB materials with reliability and miniaturization, good maintenance and interchangeability. TECHNICAL PARAMETERS: The maximum current of the controller is 40A, the limit power 2000W and the control frequency 25KHz. DC10-50V INPUT: power requirements DC10-50V, wide operating voltage range, the wiring type is the barrier type terminal block. Specification: Item Type:DC Motor Controller Material: PCB.
