12V UPS System with Dual 18650 Li-ion Battery Backup and Voltage Regulation
This circuit is designed to provide an uninterruptible power supply (UPS) system with a 12V DC output. It includes a 12V 5A power supply connected to an AC source through a toggle switch, which charges a pair of 18650 Li-ion batteries via a voltage regulator (XL4016). The UPS module ensures a continuous power supply to the load by switching between the power supply and the battery bank.

Usage Instructions
Installation
- Placement: Position the UPS in a cool, dry, and well-ventilated area.
- Connection: Plug the UPS into a wall outlet using the AC Input (Pin 1). Do not use extension cords or power strips.
- Load Connection: Connect critical devices to the UPS's AC Output (Pin 2).
- Grounding: Ensure the UPS is properly grounded using the Ground pin (Pin 3) to prevent electrical hazards.
- Communication: Connect the UPS to a computer or network using the USB or RS232 ports (Pin 4 and 5) for monitoring and configuration. If SNMP management is required, install the optional SNMP card into the SNMP slot (Pin 6).
Best Practices
- Regularly test the UPS to ensure it functions correctly during a power outage.
- Replace batteries according to the manufacturer's schedule to maintain optimal performance.
- Avoid overloading the UPS by connecting devices only up to its rated capacity.
- Use the communication features to gracefully shut down connected equipment during extended power outages.
Troubleshooting and FAQs
Common Issues
- UPS not powering on: Check the AC Input connection and ensure the wall outlet is providing power.
- Short backup time: This may indicate that the battery is depleted or not properly charged. Test the battery and replace it if necessary.
- Alarm beeping: Refer to the user manual for the specific alarm code. It may indicate an overload, battery fault, or other issues.
FAQs
Q: How do I know if the UPS is overloaded?
- A: The UPS will typically have an overload indicator (light or alarm). Refer to the user manual for specific indications.
Q: Can I replace the batteries myself?
- A: Yes, most UPS models allow user-replaceable batteries. Always follow the manufacturer's instructions and use the recommended battery type.
Q: How long will the UPS power my equipment?
- A: Backup time depends on the load connected to the UPS. Use the manufacturer's backup time chart to estimate the duration for your specific load.
