No, I'm building my own simple dual conversion UPS - the principle is the same as a commercial UPS. A 12V regulated power supply (beefy - 25A min) connected to the mains drives a 300W DC/AC (sinewave) inverter AND simultaneously maintains an AGM battery at full charge. The inverter is connected to the battery so when there's a power outage the inverter just runs off the battery rather than the power supply. I connect all equipment to the inverter of course. The benefit is I can put as large a battery as I like into the system so I can keep ruunning during an outage. Voila, isolated power to the scope
and continued running during an outage.
Hmmm, rather OT this ... what did you think of my repro?
