1. Introduction
This manual provides essential information for the safe and efficient use of your CHANZON Constant Current LED Driver. Constant Current LED Drivers are designed to supply a consistent amount of current to LEDs, ensuring optimal performance and longevity regardless of minor variations in the load. This makes them ideal for various LED applications, including floodlights, spotlights, high-power COB LEDs, and LED panel lights.
The CHANZON LED Driver series is engineered for high quality, featuring isolation protection and CE certification to ensure safety and reliability. It operates with an AC 100-240V input and provides a constant 300mA output current with an output voltage range of 3-20V, suitable for 1-6W LED configurations. Its compact design and flicker-free operation contribute to a superior lighting experience.

3. Setup and Installation
Proper installation is crucial for the safe and effective operation of your LED driver. Always ensure power is disconnected before beginning any wiring.
- Identify Connections: The driver has clearly labeled input and output wires. The input wires (Brown for Live 'L' and Blue for Neutral 'N') connect to your AC 100-240V power source. The output wires (Red for positive '+' and Black for negative '-') connect to your LED product.
- Wiring: Connect the AC input wires to your mains power supply. Connect the DC output wires to your LED load, ensuring correct polarity (Red to LED positive, Black to LED negative).
- Secure Connections: Use appropriate wire connectors (e.g., wire nuts, solder, or terminal blocks) to ensure all connections are secure and insulated.
- Mounting: Position the driver in a location that allows for adequate ventilation and is protected from moisture and extreme temperatures. The compact size allows for flexible placement within light fixtures or enclosures.
- Verify Load: Ensure that the connected LED load's voltage and current requirements fall within the driver's specified output range (3-20V, 300mA).

4. Operating Instructions
The CHANZON Constant Current LED Driver is designed for straightforward operation once correctly installed. It automatically regulates the current supplied to the LEDs, ensuring consistent brightness and protecting the LEDs from overcurrent.
- Power On: After completing all wiring and ensuring connections are secure, apply AC power to the driver's input. The connected LEDs should illuminate.
- Constant Current Output: This driver maintains a constant 300mA output current. The output voltage will automatically adjust within the 3-20V range to match the forward voltage requirements of the connected LEDs.
- Important Note: The output DC voltage can only be accurately measured under a loaded circuit (i.e., with LEDs connected). Measuring voltage without a load will result in an inaccurate reading, often showing a higher voltage than the operational voltage.
5. Maintenance
The CHANZON LED Driver is designed for long-term, maintenance-free operation. However, following these general guidelines can help ensure its continued reliability:
- Keep Clean: Ensure the driver is free from dust and debris, which can impede heat dissipation.
- Environmental Conditions: Operate the driver within its specified temperature and humidity ranges. Avoid exposing it to excessive heat, cold, or moisture.
- Inspect Connections: Periodically check all electrical connections to ensure they remain tight and free from corrosion.
- Avoid Overloading: Do not connect LEDs that exceed the driver's maximum power or voltage specifications, as this can lead to premature failure.
6. Troubleshooting
If you encounter issues with your LED driver, consider the following troubleshooting steps:
- LEDs Not Illuminating:
- Check AC input power to the driver.
- Verify all wiring connections, especially polarity (Red to +, Black to -) for the LEDs.
- Ensure the LED load is within the driver's specified voltage and current range.
- Inspect individual LEDs for damage or burnout.
- Flickering LEDs:
- Confirm the driver is not overloaded.
- Check for loose connections.
- Ensure the driver is receiving stable AC input voltage.
- Driver Overheating:
- Ensure adequate ventilation around the driver.
- Verify the LED load does not exceed the driver's maximum power rating.
- No Output Voltage (when measured without load): This is normal. As a constant current driver, its output voltage is regulated by the load. Always measure voltage with the LEDs connected.
