The input voltage must be equal to the rated voltage of the motor.Wide Voltage: Wide voltage input 10-55V, maximum output current 60A,Continuous current: 40A. Digital display :Motor Rotation Speed Percentage 0~100% ,Accurate adjustment speed.Adjust Output Current Control Motor Speed Speed Control Knob:Stepless speed regulation ,and with Forward-Brake-Reverse Switch.Only Work for Brushed Motor. Notice 1: The power of the input power supply must be greater than 1.5 times the rated power of the motor to make the motor work (note: the input voltage and the rated voltage of the motor must be consistent). Notice: If there is a forward-reverse circuit regulator on the children's car, please be sure to connect the speed controller between the power supply and the forward -reverse circuit regulator of the children's car. Otherwise, the speed controller may be damaged.
