Note the EATON Press release. Maybe the "burn on the bench" is the way they get to the California energy reduction Standards? If it isn't working it isn't using power. Date: 23 October 2012 Latest Eaton Thought Leadership White Paper Provides Technical Analysis of Eaton's Energy Saver System Eaton today announced the release of its latest white paper, "Understanding Eaton Energy Saver System." In the paper, George Navarro, an Eaton technical solutions engineering specialist, explains how Eaton's Energy Saver System (ESS) enables large uninterruptible power systems (UPSs) to operate at up to 99 percent efficiency without sacrificing reliability. Though ESS is rapidly gaining support in the UPS industry for its ability to build on the strengths of traditional double-conversion architectures, many consultants and end users have questions about how ESS works and what enables it to lower power consumption while maintaining high levels of availability. In the paper, Navarro answers these questions by providing in-depth technical information about ESS's architecture, reliability characteristics, computational infrastructure and surge suppression attributes.

I'm curious how they've worked out for you. I bought a 700VA model to give it a whirl versus the traditional APC since the Eaton is an online type with static bypass and also does some high efficiency thing where it normally stays on bypass, but the first thing it did on the bench was have the inverter/rectifier or bypass section catch on fire and destroy itself. ~Seth
