So would you advise that I do away with my power strip and just connect the AVR, westom?
I first advise answering this question. What are you trying to solve? Significant facts are obvious just by observing incandescent bulbs.
If protecting unsaved data from a blackout, then a UPS is recommended. If incandescent lamps remains more than 50% intensity, then AVR is already performed inside every electronic power supply. UPS does nothing. If noise is the problem, then a power suply is missing essentiaal funtions or a noise filter - far in excess of what anyone has discussed - is required.
If power factor is bad, well that is solved inside electronic appliances and must be corrected elsewhere to protect electric motors such as the refrigerator. If lights dim or brighten when a major appliance power cycles, then an electrician may be required to solve a serous human safety threat in household wiring.
In every case, different problems require different solutions. There is no magic box to solve all as claimed by retail salesmen and hearsay.
AVR is already performed inside every electronic appliance. AVR is only necessary for motorized appliances when utility power is defective - varies by much greater than 5% - violates international standards.
That UPS claims many functions that are also near zero. Do virtually nothing. But can be hyped to a majority as it saves the world. When claims are made subjectively - no numbers - than a majority suddenly become experts. That UPS has only one function. To protect unsave data - to a disk drive, or a movie recorded by a video recorder. It does not do fancy miracles claimed by hearsay and sales brochures.
Remember, they can lie all they want in a sales brochure. But the numeric specs must be honest. Show me the numbers.
Step one - first define a problem to be solved.
