9V 1A UPS Module - Uninterruptible Power Supply Circuit

 

9V 1A UPS Module - Uninterruptible Power Supply Circuit. It is a voltage regulator module that you can supply with DC voltage between 5-12V. It provides a constant 9V DC voltage from its output. There is a section on the circuit where you can connect a 3.7V rechargeable battery. In this way, if the power coming from the input is cut off, 9V will continue to come from the output with the voltage coming from the battery. You can continue to receive uninterrupted energy output until the battery runs out.
