That first sample of the BR800I is obviously faulty (43.6V peak-to-peak? :lol2:). The waveform asymmetry visible in the Eaton 3105 350i is also a bit disconcerting. The EPS-300PII also appears to be missing the negative half of the waveform.
Authoritarianism is for wimps.

Smart people don't buy "smart" devices without very carefully weighing up the risks and benefits beforehand.

My PC: Core i3 4130 on GA-H87M-D3H with GT640 OC 2GiB and 2 * 8GiB Kingston HyperX 1600MHz, 2 * WD3003FZEX-00Z4SA0, Pioneer BDR-209DBKS, Seasonic G-360, Silverstone PS08, Windows 7 Pro (though I do want to build a second system with GNU/Linux).

Some of the early measurements are kinda wonky, plus I usually inplug the UPS input so it does not have proper ground reference (besides the O-scope probe shielding).

The good 'ol PII only has twice the amplitude in the higher part of the cycle, the bottom one is still not 0 though. I must check it, it was kinda crazy before I started turning that knob, and I think I solved that, but sometimes my AP shuts down completely so…either the UPS (though if it was cycling as before, even the Panasonic accumulator would be dead by now), or the injector is failing (more likely).

Got three more APC units (BK650EI, SU620INET, SMT750RMI2U).

And one more, the SUA2200I.
