5. Kurulum Talimatları
- Güç Kaynağını Hazırlayın: 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.
- CilttagGereksinim: Giriş hacminizin doğru olduğunu doğrulayıntage is at least 1.2V higher than the target output voltage. Örneğinample, if you need a 20V output, provide at least 21V input. A 24V input is recommended for 20V output.
- Yükü Bağla: 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.
- İşlemi Doğrulayın: (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. Kullanım Talimatları
Once the module is set up, it operates automatically to negotiate the optimal charging protocol and power level with the connected device.
- 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 voltagve buna göre güncelleyin.
- 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.
- Standart Şarj: 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).
- 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. Bakım
- Temizlik: Keep the module clean and free from dust. Use a dry, soft cloth to wipe the surface. Do not use liquids or abrasive cleaners.
- Depolamak: Modülü serin, kuru ve doğrudan güneş ışığından ve aşırı sıcaklıklardan uzak bir yerde saklayın.
- Denetleme: Modülü periyodik olarak fiziksel hasar, gevşek bağlantı veya aşırı ısınma belirtileri açısından inceleyin.
- Yazılım: This module does not typically require user-upgradable firmware. Do not attempt to modify the internal components.
