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.<br> High-end Configuration: Our motor driver control board uses PWM modulation system to adjust light & speed. In addition, it is designed with radiators to doing heat dissipation created by MOS tube.<br> Convenient Speed Control: With wires to connect potentiometer and regulation switch to control the speed, it is convenient to use.<br> Low Quiescent Current: our speed regulation module is designed with low quiescent current 0.04A(When the working voltage is DC10V-50V, the quiescent current cannot exceed 40mA).<br> Wide Application: our 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.<br> Frequency: 15000hz<br> 12V 720w (max), 24v: 1440w (max)<br> 36v: 2160w (max), 50v: 3000w (max)<br> Standby current: 0.04a<br> Adjustment range: 5-100%<br> colour:Red<br> Material:ABS<br> size:12.2 x 8.7 x 3.2cm<br> Package Contents:<br> 1 x Motor Controller<br> Only the above package content, other products are not included.<br> Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
