Thanks Brent. I split out my discussion to a new thread over here
http://www.iceinspace.com.au/forum/s...d.php?t=132022 to avoid irritating the OP given my discussion is really on a different topic.
My current idea is to get a bench DC power supply able to meet my current requirements and more and use a smallish SLA or maybe even a larger car battery across the output to float me in case of outages.
I am looking at the moment into mounting the bench supply and battery in an enclosure so they can be wheeled out next to the scope and plugged in to mains via an extension cord. The battery would be separately charged before use on a proper multi stage charger to ensure it was in top condition and the bench supply would effectively maintain it.
If you have any thoughts could you reply in the other thread? I will copy this over there so that thread makes sense.
