UPS Battery Backup power quality
I know many members here have a lot of money wrapped up in their computers and other electronics. Many of you most likely have your equipment plugged into a UPS for protection from power spikes, brownouts, and power outages.
You always hear that electronics need clean power. Typical utility power is less than 3% THD(Total Harmonic Distortion), which is rated as clean power.
I'm sure a lot of you also use a generator during power outages. I do as well.
I have two UPS units, one is a CyberPower 1500VA AVR, the other is an APC 1500 Back-UPS XS. These are the "Line Interactive type of UPS systems. The typical UPS you will find at your local computer store.
I recently purchased a Fluke Power Analyzer to do some testing and decided to see how clean the power is from my UPS units.
The results were shocking! I think I'm going to be shopping for double conversion pure sinewave UPS units soon.
Here are the results of the output of my UPS units running on battery power.
