AVOlio wroteI've had bad experiences with PCE.
Even bad experience with MGE Eaton.
(both fried up during power switch from Generator (Ishtitak) power to EDL power, and multiple times at that after a couple of rma repairs)
Finally I tried a random brand "Focus" and it outlasted both PCE and MGE Eaton combined.
It's still alive and kicking now, and it only needs new batteries.
Same here with PCE, however MGE Eaton is great.
I have the MGE Eaton E-Series NV 2000H 2000VA UPS .
Running well since 2011 with Thermaltake 1200W PSU, 980GTX SLI, 7 HDDs, 6700k overclocked.
I had to change the battery last year but still working great.
