Perhaps I should have emphasized that the key words are “along with everything else.” I currently have 3 x 1500VA UPS units in the shack powering 3 workstations with a total of 8 LED screens, a server and all the internet gear (modem, router, WiFi, switches, etc.) as well as all the other ham gear (HF, VHF, UHF).
To create yet another full time 1000VA load (KPA500) that needs a UPS … when power is marginally needed for a couple minutes of cooling … and only occasionally … does not make any sense in my case. The feature I am asking for is already built in to the system BIOS firmware on every computer I own.
It would seem logical that Elecraft could easily implement same at virtually no material cost, and so I am offering it up as a suggestion for yet another incremental product improvement.
The UPS of 1000 watts should be able to handle the station during receive. I wouldn't plan to hold the system up during transmit. A Tripp-Lite 1500 VA UPS is $168 as found on Amazon. An APC sine wave UPS rated for 1350 VA is available for $179.
Seems reasonable to me to resolve the issue.

Unfortunately it would take a very large UPS to run the KPA500 (1000 va) on transmit along with everything else.
Sure, why not have the KPA500 on the UPS just as the other part of the station. During receive the power demand is quite low. Problem resolved.

We have a 20 kw whole house standby generator, and in addition I have everything in the shack running on a UPS (except the KPA500) in order to keep computers, etc., running for the 10-15 seconds it takes for the generator to kick in when an outage occurs.
The KPA500 goes off, of course, but does not automatically come back on when power is restored. It seems like it might be advantageous for it to resume operation in Standby mode in order to resume cooling, if it was operating when the power went out.
