Description
Description
With a unity output power factor, Liebert
ITA2 perfectly matches the needs of
modern IT loads, and with its wide input
voltage and frequency range it effectively
reduces the need for battery intervention,
thus prolonging battery life.
It is also endowed with intelligent fans with
automatic speed control, which effectively
save energy and reduce noise.
Liebert ITA2 supports common battery
configurations between paralleled UPS
and the number of batteries per string,
which can be arranged flexibly, facilitating
the utilization of different battery systems
and saving on battery investment.
An extra powerful battery charger
across all models capable of recharging
high capacity battery strings ensure a
fast charge-restoration even after a
prolonged power outages.
Liebert ITA2 offers enhanced flexibility
with a wide range of accessories for
both stand-alone and rack-mount
installations. When rack mounted,
it allows to installation of up to 40 kVA UPS
in just 3 U of space, achieving a
remarkable space saving. Parallelability
and maintenance are facilitated through
the use of dedicated maintenance
bypass option while extending the backup
time can be provided with matching
battery modules (10-20 kVA) for a neat
rack-mounted installation.
Liebert ITA2 features a multi-lingual
LCD user interface allows close
control and monitoring of the system
status and performance.
