Specification Brand : Haldzemo BulletPoint1 : Working Voltage: DC6-28V, Working Current: within 3A, Maximum Output Power: 80W, PCB Dimensions: 50mm*32mm*15mm, Potentiometer Openong Size: 8mm BulletPoint2 : With switch function with forward and reverse function, Switch cable length: 15cm BulletPoint3 : Control the forward or reverse direction and the stop of DC motor by switch. BulletPoint4 : The input of the DC motor speed controller is DC power, and it cannot be directly connected to AC power (such as household 220V AC), otherwise it will burn out! BulletPoint5 : Do not reverse positive and negative power loads. This will damage the controller!

Note that this is not a power module, must be connected to the motor in order to adjust the speed, not connected to the motor multimeter output did not change. Connect the motor can not be divided into positive and negative, when the running direction is not consistent with the expectation, you can adjust the wire sequence to change the direction. Note: 1. This governor is for the use of DC brush motor. 2. It is not suitable for the speed regulation of DC brushless motors; nor can it be used as a voltage regulator or voltage stabilizer!
