Características principales

• Uninterruptible Power Supply (UPS) Functionality: Seamlessly switches to battery power upon external power failure.
• Carga integrada: Supports charging of 3.7V lithium batteries (4.2V fully charged).
• Protección de la batería: Includes overcharge, over-discharge, over-temperature, and over-current protection for enhanced battery safety and longevity.
• Potencia de salida: Proporciona un volumen de salida establetages (5V/9V/12V) for various devices.
• Entrada de energía flexible: Features a Type-C charging port (max 5A) and direct DC5V input.
• Indicador LED: Green LED indicates full charge, with automatic charging stop.

2. Conecte la fuente de alimentación: Connect a 5V power source to the module using either the Type-C charging port or the direct DC5V input terminals. The maximum input current for Type-C is 5A.
3. Conectar carga: Connect your 5V, 9V, or 12V device to the output terminals of the module. Ensure the load power does not exceed 15W. Refer to the specifications for current limits at different output voltages.

Instrucciones de funcionamiento

• Funcionamiento normal: When external power is connected, the module will directly power the connected load via its boost circuit and simultaneously charge the installed lithium batteries.
• Función SAI: In the event of an external power failure, the module will automatically and seamlessly switch to drawing power from the installed 18650 batteries to continue powering the load. There is no noticeable delay during this transition.
• Indicador de carga: During charging, the LED indicator will show the charging status. Once the batteries are fully charged, the green LED will illuminate constantly, and the charging process will automatically cease to prevent overcharging.
• Load Power Limit: Ensure that the total power consumption of the connected load does not exceed 15W. Exceeding this limit may cause the module to malfunction or damage.

Mantenimiento

• Cuidado de la batería: Use only high-quality 18650 lithium batteries. Avoid mixing old and new batteries or batteries of different capacities.
• Características de protección: The module includes built-in overcharge, over-discharge, over-temperature, and over-current protection. Do not attempt to bypass these safety features.
• Limpieza: Keep the module clean and free from dust and moisture. Use a dry, soft cloth for cleaning.
• Almacenamiento: If storing the module for an extended period, remove the batteries and store them separately in a cool, dry place.

Solución de problemas

• Sin salida de potencia:
  • Compruebe si las baterías están correctamente instaladas y cargadas.
  • Verify the external power supply is connected and functional.
  • Asegúrese de que la potencia de carga no supere los 15 W.
  • Inspect all connections for proper contact.
• Baterías que no se cargan:
  • Confirm the external power supply (Type-C or DC5V) is providing 5V.
  • Check the LED indicator for charging status. If it's constantly green, batteries might already be full.
  • Ensure batteries are properly seated and not damaged.
• Sobrecalentamiento del módulo:
  • Reduce the connected load. The module has over-temperature protection, but continuous high load can cause heat.
  • Asegúrese de que haya una ventilación adecuada alrededor del módulo.
