small, din-railable UPS reccomendations?

[kjkoster]

Dear All,

We are looking for a small UPS for the Revolution Pi plus its 4G modem (we use RUT24, if that matters). Does not have to be super powerful, it would be nice to give the revpi a minute or two for it to be able to send a message that the power went out and perform a graceful shutdown.

Requirements: DIN-rail, 24V, some kind of output signal that we can feed into the revpi to trigger shutdown behaviour.

Nice to have: cheap.

I have exactly the same question. Since this is a question from a month ago what did you end up using? Or are you still looking?

Dear S_wauters,

Still looking.

For another project, where we use regular Raspberry Pi's, I use a beefy, but otherwise plain power bank. Be sure to get one that supports pass-through charging. Also: source locally, because many of the on-line ads overstate the actual capacity of the power banks.
