For my remote tracking rig, I'm on the hunt for something that takes whatever garbage is coming in, stores it (in big caps?) and then regenerates a perfect AC sine wave for my gear (120v/15A) on the output....much like they do for sensitive medical equipment. That would be ideal.
Unfortunately, I don't have the technical vocabulary to "specify" what I'm after so if someone gets what I'm saying and knows the term for it (online, double-conversion?), I'm all ears!
To me, the power goes OUT so rarely, I'm not worried about having batteries or a UPS. I'm more worried about having stellar power 99.99999% of the time.
I've been happy with my Furman AR15, which is silent but pricey for what it does!
