For my eventual pier and obs setup I have been thinking about a bench DC power supply, potentially fed via a UPS on the AC side so it does not drop if there is a mains interruption.
The UPS could potentially supply any AC fed gear at the same time to keep everything up and running but for things like a laptop that would be a bit belt and braces as it would just drop to battery anyway.
The other way I could see to do it would be the bench supply but with moderate sized SLA battery across the output to pad through any interruptions, the problem with that would be the need for the supply to be on constantly to keep the battery trickle charged, but then that is what an UPS would be doing as well.
In my case it is probably overkill, given that I am purely a visual observer a brief loss of power is an inconvenience more than anything else, at worst it would result in having to redo a star alignment on a goto mount.
