I am looking for a simple small UPS to maintain power to my Wolsey
antenna amplifier. It plugs into a standard mains socket, and
has two F-type connections for the In and Out co-ax cables. All I need
is a simple single-outlet 3-pin UPS that I can plug into the mains
outlet, and then to plug the Wolsey into that. But I can only find
small UPSs that have DC outputs, which is not what I want, I want
to maintain AC power to the Wolsey if mains power fails.
I can go to APC and Eaton, and buy large units designed to power a
computer system, but not one that I can buy as a stand-alone plug-in
unit equivalent of a 12v line-out UPS. The location of the Wolsey is
way too far from my computer room to even consider running a cable up
there.

Any ideas welcome.

Is this Wolsey a combination PSU & RF amplifier or is it a PSU that is powering a masthead amplifer on the antenna pole itself?

Reason I ask is because there may be another possible solution for you.

It is a Wolsey WMA-WPS 100/1 unit. There is something on the antenna,
but I have never climbed up to look at it! Even my roofer thinks twice
about going up there. It might just be a junction box, it might be an amplifier.
But there is a unit in the loft, which distributes the signal to
different destinations, four of them, I believe.
My Humax puts out 5v, so cannot help in this situation, the Wolsey
needs 12v.

Correction: The Wolsey puts out 12v, it needs 230/240 VAC.
Thinking (on a Sunday, no less), the unit itself is probably just the
PSU, the unit in the loft is an amplifier/distributor. Or the thing on
the antenna is an amplifier, the thing in the loft is a distributor.

That is a masthead power unit that produces 12 v.

You could replace this with a DC inserter such as https://www.matyco.com/en/fracarro-power-inserter-with-3a-current-female-f-connector-287612

and then use a 12Volt UPS such as https://www.se.com/uk/en/product/CP12036LI/apc-backups-connect-12vdc-36w-lithiumion-mini-network-ups-to-protect-internet-routers-ip-cameras-and-more/


and power the UPS with a 12 volt laptop PSU such as

https://www.amazon.co.uk/12-volt-power-supply/s?k=12+volt+power+supply

You would then need to make an adaptor to tale the output of the UPS to
an F plug.

Thanks. Not quite was I was hoping for, but....
-u9 (+shipping?) + -u68 + -u7 = ~-u85--u90.
Plus converting output to F-plug. I have plenty of those in stock.
Worth thinking about.
A shame what I wanted isn't available, I was hoping for a mains plug
and socket version of the APC unit.
