Toshiba with its
Pentadyne partner provides UPS rated from 100 to 300 kW that do not
need batteries. A flywheel provides the DC support. This eliminates the
recurring cost of battery replacement. This is a Highly Green Solution
in that it eliminates the use of hazardous lead and acid in multiple batteries. This
eliminates not only the first implementation of batteries but also several
replacements required over the life of a UPS System.
