How do I connect a power supply to a battery backup?

This isn’t a problem if the backup power system is very rarely used. Using the battery backup circuit that I designed, you can plug your power supply into a female DC power connector. This is connected to the battery backup circuit.

Can I use a battery if I'm using a power supply?

When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.

What can you do after creating a power supply?

After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more. This is a good way to learn how basic electronic components can be put together, like a puzzle, to accomplish a task.

What kind of power supply do I Need?

A 9V, 5V and 3.3V stable supply that you can take anywhere with no country adapters or spare cables. If you're flying and weight is an issue, you can always pop the batteries out making it super light. Acknowledgements

What does a power supply do?

A power supply is responsible for providing a circuit with all the power it will need during normal operation. It provides the circuit with a certain voltage and current. The best way to think of this would be to imagine a hose with water running through it.

How many volts can a power supply supply supply?

The power supply, which comes as a kit with THT type components and a PCB (so its easy to solder), takes in 24V AC supply at its input and gives between 0-30V at its output depending on user input via an onboard potentiometer. The module is able to supply up to 3A current and is equipped with safety features that help prevent overload and shorts.
