Uninterruptible power supply UPS

It has been verified and can be used as a board. The input voltage is 9-12v. Please adjust the battery pack yourself.

If you are a student and are fed up with the problem of power outages and Internet disconnections in dormitories every night,

If you are a NAS user and cannot accept data loss caused by sudden power outage,

Come on, this project is tailor-made for you. It only requires a few components to solve your worries.

First of all, you need a 12.6v battery pack and the PCB for this project. You may also need an automatic step-up and step-down module to stabilize the output voltage of the battery pack at 12V.

Take a 12V powered router as an example:

Insert the battery's regulated output end into the 12.6-BATTERY socket.

Plug the power adapter into the 12V-DCIN socket,

Solder an output wire to any one of H1-H4, and connect the other end to the router.

When there is a power adapter input, the router is powered by the power adapter and the battery is disconnected.

When there is a power outage, the battery is plugged in to start supplying power.

The CHARGE socket on the board is used to charge the battery. It is not recommended to leave the charger plugged in all the time.
