Title: APC does not make them like they used to
Product review: We have an SUA750 at work so I looked at its waveform output (using an oscilloscope) with a desktop computer and LCD monitor running from the backup. When I disconnected the SUA750 from the power grid and it switched to battery, it did NOT provide a perfect sine wave output. The crests and troughs were flattened for approx. 10% of the voltage amplitude (top and bottom each). Along with the flattening there was a small ripple on the leading edges. If APC is going to charge a premium for SmartUPS's they should step up the quality of the output. I can remember a time when the original BackUPS and SmartUPS's produced good sine waves when on battery and were worth the extra cost.
Would you say this review depicts the product in a flattering or unflattering light?
