3 out of 5 eggsGood AC Sine Wave

This review is from: CyberPower Sinewave PR750LCD 750 VA 525W 6 Outlets Mini-tower UPS

Pros: The sine output is as advertised and is very good. I have a device to measure the output on a scope. The AC output is a good sine wave when charging and during pass thru (AC in). Cool display showing power usage.

Cons: Two of the last three units I purchased were broken on arrival. One had missing pixels on the display that were annoying but worked. One would appear to turn on but never provide power to the outlets. This appears to be a safety startup mode to keep from running the battery down. I own several other CyberPower products and am aware of this feature. After charging for days and recycling it still would not turn on the outlet power. Appears stuck in safe mode.

The common mode, and normal mode noise on this device is high. I have several low impedance isolation transformers that I could place on the AC outlets and run my computers and devices thru the isolation transformer. The noise should be in the mV range and was in the V range coming from the CyperPower. Using the isolation transformer returned the noise levels back to the mV range.

I do not like the user interface of the buttons and display. It is usable but not enjoyable.

Other Thoughts: CyberPower appears to have solved one of the major issues with UPS power and that is a clean Sine Wave. However the noise produced can still produce hard to trace issues with low voltage electronics. A low impedance isolation transformer can solve those issues but cost $400-600 more and are another piece of equipment to manage.
