Note:
1. The input of the DC motor speed controller is direct current, and cannot be directly connected to alternating current (for example: household 220V alternating current), otherwise it will burn out! ! !
2. Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.
3. The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.
4. Adjusting the potentiometer knob can change the duty cycle of the governor output and the motor speed.

Features:
1. This DC motor speed controller allows controlling the direction of a DC motor using a Pulse--Width-Modulated (PWM) DC voltage with a duty cycle fully adjustable from 0%-100%.
2. The motor speed controller can easily provide a continuous current of 3A to your DC motor or other DC load.

Specification:
Input Supply Voltage: 6V-28V DC
The Maximum Output Power: 80W
The Maximum Continuous Output Current: 3A
Duty Cycle Adjustable: 5%-100%

Operating Instruction:
1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram.
2. Connect a voltage of 10V-36V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits.
3. You can now control the speed of the motor through potentiometer.
