How It Works

1. Power Connection – Connect 12V–48V DC to the input terminals.

2. Motor Connection – Wire the motor to the output terminals (observe polarity for direction control).

3. Speed Adjustment – Use the potentiometer or an external PWM signal (e.g., from Arduino) to set speed.

4. Direction Control – Toggle between forward, reverse, and braking modes.
