Mini 5A PWM DC Motor Speed Controller Module (3V–35V) – LED Dimmer Switch

Product Description:

Mini 5A PWM DC Motor Speed Controller Module (3V–35V) – LED Dimmer Switch

The Mini 5A PWM DC Motor Speed Controller Module is a compact, efficient, and versatile solution for regulating DC motor speed or dimming DC-powered LED lights. Based on PWM (Pulse Width Modulation) technology, this controller allows you to adjust motor speed or brightness precisely, making it ideal for applications like cooling fans, LED dimming, motor-driven automation, and more.

This module supports a wide input voltage range of 3V to 35V DC and delivers up to 5A of continuous current, protected by a self-recovery fuse for safe and stable operation.

📝 Usage Instructions:

1. Turn the potentiometer fully counterclockwise until a click is heard.

2. Connect your motor or LED to the ‘MOTOR+’ and ‘MOTOR-’ terminals.

3. Supply DC power via ‘DC IN+’ and ‘DC IN-’.

4. Adjust the knob to vary speed or brightness as needed.

5. To stop output, rotate the potentiometer fully counterclockwise again.

⚠️ Important Notes:

• Works only with DC motors or DC LEDs—do not connect to AC (110V/220V).

• Observe correct polarity—reversing polarity may damage the controller.

• Motor rotation direction can be reversed by swapping the motor wires.
