I have a refrigerator that is 24v dc powered. It is currently running off of a 110 to 24v power supply. I am building a 24v LiFePo4 battery to power it when the power fails. I would like to find a device where by it switches between two different 24v sources in order to power the refrigerator no matter what happens.
It does not need to charge a battery, or anything else for that matter. Just automatically switch between 24v DC sources. Does such a thing exist?
Also, does a 24v DC circuit failure alarm exist? IE, like the devices you can plug into an outlet or power strip which will sound a siren or buzzer when they lose 110 power - as they have a 9v for the siren when power goes out.
Thanks for reading!
