    Hmm!   Looks like the same picture here but offered for $75.00.   Ebay is $275...

    It is a mouth full product name.  What does it do?  Regulate the line voltage and filter harmonics?  May work fine for audio and looks like it is bullet proof if not beyond its flight hours before scheduled maintenance.

    The first $75 figure is for shipping. The price is $275 as in the ebay listing

    Is it some kind of constant power supply?

    Yes, $275 thanks....  I think it works both ways upstream or downstream for harmonic filters.  Keeps downstream motors and inductive load switching from junking up the incoming AC and filters harmonics from the line and regulates line voltage as well before use.

    "Harmonic currents, or harmonics as they are better known, are a result of a distorted electrical waveform, generally created by non-linear loads.  Some of the more common causes of unwanted harmonics are variable speed motors, variable frequency drives and inverters, industrial battery chargers, some personal computers, and even those small portable uninterruptable power supplies.  Harmonic neutralizers can be incorporated into some constant voltage transformers primarily to clean up harmonic distortion. To keep it simple, these neutralizers basically absorb harmonic power and emit heat as a by-product."

    Deepee... this may be what you need to filter/ regulate voltage when the electric mining shovels start up in your neighborhood.

    Think I've got enough fire-hazards in the house already . . . Smile

    Sola is still with us, and that beast *could* be useful under some conditions. But, not $350-worth to my way of thinking.

    Too rich for my blood, plus not sure I could sneak it past She Who Will Be Obeyed. 4.5 amp outlets kinda put a damper on things, too.
