I am looking for a module that I can use as a 12V (around 5A max) power supply that will fall back to a simple 12v 6Ah type AGM.
My intent is to power the Raspberry PI circuit that I use to control the actuator that I use to open my chicken coop door. At full load these devices could use up about 5A at 12v. The motor only has to run a few time a day, but I'd like to keep the Pi circuit up for a few hours (maybe it's using around 300ma).
I have a small switcher to convert the 12v to 5v for the PI, and I tried using an off the shelf plugin battery charger, but those things seem to switch off after a while.. Any advice on a module that can do the job..
something that has 120v in, Battery +/- and 12v Power Supply out +/-
I thought that these things were fairly common, but I am striking out on web searching..
many thx.
