  Steps to Use:  

1. Turn the potentiometer counterclockwise until you hear a sound.
2. Connect the DC motor or lamp to 'MOTOR+' and 'MOTOR-'.
3. Connect the DC power supply to 'DC IN+' and 'DC IN-'.
4. Adjust the knob to control the motor speed.
5. To stop, turn the potentiometer counterclockwise until you hear a sound.
6. Remove the power supply before removing the DC motor.

  Applications:  

• Industrial DC motor speed regulation.
• Industrial conveyor belt speed regulation.
• Lighting and dimming control.
• Computer power supply cooling.
• DC fan speed control.

  Note:  

• Only use with DC motors and DC power supplies; do not connect to AC power.
• Ensure correct polarity when connecting the DC power supply.
• The potentiometer knob adjusts the output duty cycle, changing the motor speed.
