- Connect Transmitter: Connect a 5V DC power source to the input wires of the transmitter module. The red wire is typically positive (+), and the black wire is negative (-). Ensure the power source can provide sufficient current for your application.
- Connect Receiver: Connect the output wires of the receiver module to your 4.2V lithium battery or other compatible device. The red wire is positive (+), and the black wire is negative (-).
- Position Coils: Place the transmitter coil and receiver coil in close proximity. For optimal performance, align the centers of the coils. The effective charging distance will vary based on the application and coil alignment.
- Power On: Apply power to the transmitter module. The receiver should begin charging the connected battery or powering the device.
Operating Instructions
Once the module is set up, operation is straightforward:
- Ensure the transmitter is powered and the receiver is connected to the device requiring power.
- Maintain a consistent distance and alignment between the transmitter and receiver coils for stable power transfer.
- Monitor the charging status of your battery or the operation of your device.
Optimal Performance Tips:
- Minimize the distance between the coils.
- Avoid placing metallic objects between the coils, as this can interfere with power transfer and generate heat.
- Ensure the power supply to the transmitter is stable and within the specified 5V range.
Maintenance
The Taidacent XKT-R02 module requires minimal maintenance:
- Keep the module clean and free from dust and debris.
- Regularly inspect wiring for any signs of damage or loose connections.
