Energy Advantage Architecture (EAA)
The rising demand for highly available, reliable and efficient power
is a continuous challenge for data centre operators. Higher energy
efficiency helps to address increasing environmental, regulatory
and economic pressures.
Eaton has developed innovative and proprietary technologies that
improve system efficiency without compromising on reliability
under the Energy Advantage Architecture (EAA) umbrella.
Typical field operations are usually within low load range, but UPSs
do not operate at optimal efficiency when used for lighter loads.
In some multi-UPS parallel systems used with lighter loads, the
system maximises the load percentage of the UPSs by putting the
UPSs that are not needed to power the load into idle mode. This
results in partial energy savings and is limited to multi-UPS sys-
tems, with no efficiency improvements for single-UPS systems.
Variable Module Management System (VMMS) technology
maximises efficiencies at lighter loads without compromising
reliability.
