Operating voltage range is DC 10-50V, max rated current is 60A, control range is 0.01-3000W, working temperature range of -20C to 40C. High-end Configuration: Our motor driver control board uses PWM modulation system to adjust light and speed. It is designed with radiators for heat dissipation from the MOS tube. Convenient Speed Control: Equipped with wires for potentiometer and regulation switch to control speed easily. Low Quiescent Current: The speed regulation module has a low quiescent current of 0.04A (when working voltage is DC 10V-50V, quiescent current does not exceed 40mA). Wide Application: Suitable for universal DC brush motor speed regulation, car motor speed regulation, production line conveyor belt speed regulation, electronic fan speed regulation, etc. Frequency: 15000Hz Power ratings: 12V 720W (max), 24V 1440W (max), 36V 2160W (max), 50V 3000W (max) Standby current: 0.04A Adjustment range: 5-100% Color: Red Material: ABS Size: 12.2 x 8.7 x 3.2cm Package Contents: 1 x Motor Controller Note: Light and different displays may cause the color of the item to vary slightly from the actual product. Measurement allows an error of +/- 1-3cm.
