Protection measures Automatically activates the battery path during power loss and provides protection against short circuit, overvoltage, and undervoltage for enhanced safety. Efficient power supply switching Lithium battery charging module with UPS circuit enables seamless transition between main supply and battery without delays. Charging status indicator A color LED indicates charging status: green shows full charge, and charging stops automatically when full. UPS uninterruptible power supply When mains power is available, the main supply feeds the load directly through the circuit for continuous operation; during power loss, the battery supplies the load through the UPS circuit to maintain operation. Key benefits Ensures continuous operation of critical devices, reducing downtime and potential data loss. Provides safety protections against short circuits, overvoltage, and undervoltage. Enables fast, seamless switching between power sources without interruptions. Clear charging status indication helps manage battery life and charging cycles. Compatibility and performance notes Designed for lithium battery charging with an integrated UPS circuit for reliable power management. Suitable for use with lithium battery packs and UPSenabled setups requiring uninterrupted power supply. Applications Home electronics and small office equipment such as routers, modems, NAS, and media players during power outages. Security and monitoring systems like CCTV cameras and alarm panels that need continuous uptime. Embedded projects or DIY systems requiring reliable power switching and safe battery charging with UPS functionality.
