The input of the DC motor speed regulator must be DC input, cannot be connected to AC input (e.g. Household AC 110V), otherwise, the motor speed regulator will be burnt. Polarity of motor: No need to distinguish the positive side and the negative side when you connect the motor and you can adjust the order of the wires to change the direction. Working Voltage: DC 6V - DC 90V (Ultra wide working voltage) ; Control Power: 0.01 - 1000W(Max current :15A) The board can control motor speed to change between 0% to 100% With Power supply reverse polarity protection,voltage overvoltage Protection,15A fuse Static Current: 0.005A ( Standby) ; PWM Duty Cycle: 0% -100% ; PWM Frequency: 15Khz . Package: 1 x motor speed controlle + Potentiometer 100K + knob
