These are industrial grade power conditioning units that mount in the electrical panel across both phases. They provide whole house surge protection, wave form correction and noise reduction. I am selling these because I have moved to a smaller house with one panel from a large house that had 3 panels.
See Environmental Potentials web site for more details (
http://ep2000.com ). There are also some good reviews out there including one from Dr. Bill Gaw.
The 2700 sells new for $800. I will sell for $400. (See
http://ep2000.com/uploads/EP-2700%20Specifications.pdf for more details). This 2700 is the previous version which can be installed standalone....it does not require the installation of a 2000 or 2050.
The 2050 sells new for $450. I will sell for $sold. (See
http://ep2000.com/uploads/EP-2050_SeriesSpecifications.pdf for more details.)
