I think I might have found a solution on Rod Elliot's excellent website.
It is DIY a veroboard solution, but seems to fit the bill because it uses a normally open relay for the Mains In/Out to the load. If the Mains voltage varies outside the settings the relay opens. I will investigate further.

That's different I thought it was when the power was coming back on, bear in mind how quick a UPS kicks in, you would have to find a UPS with a very quick responds time. From what I have been reading they seem to be very noisy even when not in use, so this may affect the sound quality. The one my mate was using was an old one but with new batteries and it was very noisy, I asked him if he thought it would affect the sound from his HiFi and he said most definitely. One thing you could do is add a mains conditioner after the UPS unit.

I've got Raspberry Pi based media server, Arduino nano, hi-fi, router etc running 24/7 . We get power outs moderately frequently but no equipment failures so far. I suspect your problems have more to do with your power supply designs. You may be seeing issues due to device latch-up

Thanks Geoff, I well remember visiting you, down the road from my Cousin in Mylor Bridge.
The component failures I have had seem to be related to the spikes associated to the failing supply as it disappears. I hear my setup trying to turn on/off/on/off. Not sure what device would protect from that other than a UPS.

As gwebster said, my mate would agree with him, He had one for his wife whom was working from home when in lockdowns and they had a power cut and he was vary disappointed that his UPS only lasted hour and half and he said his was the size of two suitcases. I still think a good surge protection is what you need.

Back when I was living within a village in Cornwall and working from home with a desktop computer, I invested in a UPS. It was as big as the desktop box and would only give about an hours backup in the case of a power outage. My hi-fi was left to fare for itself. During that time, we had one or two outages and everything worked fine. When we moved within Cornwall to a more rural setting, a converted stables within a country estate (which you visited once to look at my Genera pre), we suffered a few more power outages but never any equipment failures due to them. Now we live in rural Hampshire in the South Downs and get more frequent power outages (more trees?) and, judging by the occasional few second tripping of my mains protection circuitry within my power amp, brown-outs.
The only time I've suffered equipment failure has been due to phone/power surges from lightning strikes locally (fried modem). I suspect your problems are due to power surges / spikes. As others have suggested, a decent surge suppression power block is likely to be your best solution.

I think something with only surge protection is what you should be looking for, one where you can switch off your most vulnerable equipment. Like Jon said you may find something with UPS will affect the sound quality and if the power is out for a long time say hours your going to need a UPS with a long battery life. Mains plugs with suge protection are cheap but I would advise going for the best you can afford with your sircumstances. I can't offer much more advice really.
