2. Safety Information

WARNING: Failure to follow these safety instructions could result in fire, electric shock, injury, or damage to the product or other property.

• Ensure the input voltage is within the specified range (9-28V DC).
• The input voltage must be at least 1.2V higher than the desired output voltage. For a 20V output, an input of 21V is required (24V recommended).
• Do not exceed the maximum output power of 140W (28V@5A).
• Handle the PCB module with care to avoid damage to components.
• Do not expose the module to moisture, extreme temperatures, or corrosive environments.
• Ensure proper ventilation when operating, especially at high power outputs.
• This product is a component and requires appropriate enclosure and integration for safe use in end applications.

5. Setup Instructions

1. Prepare Power Source: Connect a DC power source (e.g., car battery, power adapter) to the 'IN: 9~28V DC_IN' terminals or the 'PD_IN' Type-C port. Ensure the power source can provide sufficient voltage and current for your desired output.
2. Voltage Requirement: Verify that your input voltage is at least 1.2V higher than the target output voltage. For example, if you need a 20V output, provide at least 21V input. A 24V input is recommended for 20V output.
3. Connect Load: Connect your device (e.g., laptop, smartphone, power bank) to one of the output ports ('C_Out' Type-C or USB-A, depending on your module variant). Use a high-quality cable that supports the desired power delivery and fast charging protocols.
4. Verify Operation: (Optional, but recommended) Use a USB power meter (as shown in Figure 4) to monitor the input and output voltage/current and confirm that the correct fast charging protocol is engaged.

6. Operating Instructions

Once the module is set up, it operates automatically to negotiate the optimal charging protocol and power level with the connected device.

1. Automatic Protocol Detection: The module will automatically detect the fast charging protocol supported by your connected device (e.g., PD3.1, QC5, AFC) and adjust its output voltage and current accordingly.
2. High Power Charging: For devices supporting PD3.1 EPR, the module can deliver up to 140W (28V@5A) provided the input power source is sufficient.
3. Standard Charging: For devices or cables that do not support EPR, the module will default to standard PD3.0/2.0 or other supported protocols, typically delivering up to 60W (20V@3A).
4. Multiple Outputs (AC variant): If using the AC variant with both USB-A and Type-C outputs, the total power output will be shared between the ports. The module intelligently manages power distribution.

Note: The actual charging speed and power delivered will depend on the capabilities of your device, the quality of the charging cable, and the capacity of your input power source.

7. Maintenance

• Cleaning: Keep the module clean and free from dust. Use a dry, soft cloth to wipe the surface. Do not use liquids or abrasive cleaners.
• Storage: Store the module in a cool, dry place away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the module for any signs of physical damage, loose connections, or overheating.
• Firmware: This module does not typically require user-upgradable firmware. Do not attempt to modify the internal components.

8. Troubleshooting

9. User Tips

• For optimal 140W performance, ensure your power source can deliver sufficient current at 28V, and use a certified PD3.1 EPR compatible cable and device.
• When integrating into a custom enclosure, ensure adequate airflow around the module to prevent thermal throttling, especially during prolonged high-power operation.
• Consider using a USB power meter to verify the actual voltage and current being delivered to your device, which can help diagnose charging issues.
