PWM DC Motor Speed Controller DC 9V 12V 24V 48V 60V 20A Reversible Motor Speed Controller Regulator Driver PWM

Input voltage: DC 9-60V (specific voltage should be equal to the motor rated voltage) Input current: requires more current than the motor Output voltage: linear under load Output current: 20A Continuous current: within 18A Working frequency: 25KHZ Forward rotation reverse: support   Note: Electric motor can not be used The input voltage should be equal to the rated voltage of the motor. The input voltage must be positive and negative Red line is power supply Black line is negative for power Blue-Green motor is not divided
