$21,287 of savings for 15 years of operation
actually be achieved when considering cooling as well. Translating
into emission of CO
represents a reduction of 285,243 lbs of CO
Besides the energy savings, another environment-friendly feature is
the reduction of electromagnetic noise owing to the innovative
three-level circuit concept and its exclusive power module. Since
environmental regulations change from time to time, the G9000 UPS
is the most suitable long-term power protection solution to stay ahead
of the future.

Better utilization of available space
Its transformerless, all-transistorized, three-level circuit design results
in a high power density UPS with small footprint and low weight. The
225kVA G9000 UPS occupies an area of 8.11 square feet (7,542
square centimeters) and weights only 1230 lbs (558 kg). These
characteristics promote a considerable reduction of shipment costs
when compared with conventional UPS with similar specification. Its
small footprint facilitates reconfiguration if needed and helps to save
space and infrastructure in expensive environmentally controlled
facilities.
