The Symmetra
TM
is a high-performance, uninterruptible
power array system, designed for large-scale loads. It pro-
vides conditioned, reliable AC power to load equipment, and
provides protection from power blackouts, brownouts, swells,
sags, surges and interference. The Symmetra
TM
Power Array
system is comprised of either a MiniFrame, or a MasterFrame,
and a variable set of modules. A MiniFrame system can be
configured to deliver a maximum output of 8kVA, and a
MasterFrame system can deliver a maximum of 16kVA.
