Introduction
This manual provides instructions for the Gaqqee DC Motor Speed Controller and LED Dimmer module. This versatile device allows for stepless speed regulation of DC motors and dimming of compatible LEDs using Pulse Width Modulation (PWM) technology. Please read this manual carefully before installation and operation to ensure safe and efficient use.
Safety Information
- Ensure the power supply voltage is within the specified range (DC 5V-16V).
- Do not exceed the continuous current of 10A or the short maximum current of 20A (for less than 10 seconds).
- Always disconnect power before making any wiring connections.
- Incorrect wiring can damage the module and connected devices.
- Keep the module away from moisture and extreme temperatures.
- This device is intended for low voltage applications (below 50Vac or 75Vdc).

Setup
Before connecting, ensure your power supply and load (motor or LED) are compatible with the module's specifications (DC 5V-16V, max 10A continuous current).
- Identify Terminals: The module has two sets of terminals: one for 'Power' input and one for 'Load' output. The '+' and '-' markings indicate polarity.
- Connect Power Supply: Connect the positive (+) terminal of your DC power supply to the '+' terminal of the 'Power' input on the module. Connect the negative (-) terminal of your DC power supply to the '-' terminal of the 'Power' input.
- Connect Load: Connect the positive (+) terminal of your DC motor or LED to the '+' terminal of the 'Load' output on the module. Connect the negative (-) terminal of your DC motor or LED to the '-' terminal of the 'Load' output.
- Verify Connections: Double-check all connections for correct polarity and secure wiring to prevent short circuits or damage.
Operating Instructions
- Power On: Once all connections are secure, apply power to the module.
- Adjust Speed/Brightness: The module features a potentiometer (rotary knob) for control.
- Switch On/Off: Rotate the potentiometer clockwise from the fully counter-clockwise (0%) position. You will hear a click, indicating the module is switched on.
- Stepless Control: Continue rotating clockwise to increase the motor speed or LED brightness from 1% to 99%.
- Switch Off: Rotate the potentiometer fully counter-clockwise until you hear a click. This will switch off the module, and the output will be 0%.
Note on LED Dimming: When using for LED dimming, ensure the LED can operate directly from the power supply. If the LED is directly connected to a power source that would cause it to burn out without the dimmer, a series current-limiting resistor is typically required. If unsure about the required resistance, consult customer service.
Maintenance
- Keep the module clean and free from dust and debris.
- Store in a dry environment to prevent moisture damage.
- Avoid exposing the module to strong vibrations or impacts.
- Do not attempt to disassemble or modify the module, as this will void any potential warranty and could lead to damage or injury.
Troubleshooting
- No Power/No Control:
- Check all wiring connections for correct polarity and secure contact.
- Ensure the power supply is providing the correct voltage (DC 5V-16V).
- Verify the potentiometer is rotated clockwise past the 'off' click position.
- LED Dimming Issues:
- If using for LED dimming, ensure the LED is compatible with PWM control.
- If the LED burns out, it may require a series current-limiting resistor. Consult the 'Operating Instructions' section or contact customer service for guidance.
- Unexpected Current Draw:
- When the potentiometer is in the 'off' position (fully counter-clockwise), the module draws a very small current (0.002A). This is normal and indicates no current is supplied to the load.
User Tips
- Users have reported that the module is easy to install and performs well, indicating good quality and straightforward operation.
- For projects requiring precise control, familiarize yourself with the potentiometer's full range of motion.
