Operating voltage range is DC 10-50V, max rated current is 60A, control power range is 0.01-3000W, working temperature range of -20Celsius-40Celsius.High-end Configuration: motor driver control board uses PWM modulation system to adjust light and speed. In addition, it is designed with radiators to doing heat dissipation created by MOS tube.Convenient Speed Control: With wires to connect potentiometer and regulation switch to control the speed, it is convenient to use.Low Quiescent Current: speed regulation module is designed with low quiescent current 0.04A(When the working voltage is DC10V-50V, the quiescent current cannot 40mA).Wide Application: motor driver control board can be applied to universal DC brush motor speed regulation car motor speed regulation production line conveyor belt speed regulation electronic fan speed regulation etc.Frequency: 15000hz12V 720w (max), 24v: 1440w (max)36v: 2160w (max), 50v: 3000w (max)Standby current: 0.04aAdjustment range: 5-100 percent colour:RedMaterial:ABSsize:12.2 x 8.7 x 3.2cmPackage Contents:1 x Motor ControllerOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
