Rack/Tower Configurable UPS For Network Protection

Compact UPS Systems For High Power Network Rack Applications

Liebert GXT2 10 kVA

Today’s converged networks require increased availability and reliability. This has created a need

for higher density power protection systems that adapt to mixed load voltages and plug types, while

remaining easy to install and maintain.

New IT technologies, such as VoIP and PoE, have greatly increased power demands.
Unfortunately, as these requirements have risen, the amount of space available for your
protected equipment and related power support systems has not.

The ever-increasing global reach of businesses is also making it more advantageous to
standardize on power systems that can be used in a variety of input and output configurations.

Liebert Solutions

To meet these needs for higher
capacities in smaller spaces we have
developed the Liebert GXT2 6 kVA
and 10 kVA UPS systems. These true
on-line double conversion UPS systems
feature integrated maintenance
bypass, as well as optional extended
battery runtime. Add support —
Emerson Network Power Service—
and it all equals greater power
assurance and reliability.

Output

Designed for use in either rack or
tower configurations, both units
offer the smallest available solutions
for these power capacities — the
6 kVA model at 120/208V output in
4U size, or the 10 kVA unit 120/208V
output in a 6U package.

To help meet the need for choosing a
single supplier for global applications,
220V, 230V and 240V 50/60 Hz
models are offered with CE and
C-tick markings.

Dual Voltages For Multiple
Applications

Simultaneous output voltages
of 240/120, 208/120, 230/115,
220/110, or 200/100 VAC provide
the flexibility to adapt to multiple
load requirements without the need
to add additional transformers that
take up extra space and add weight.
Input power factor correction to

0.98 reduces current harmonics
and their heating effects.

Liebert Delivers 6 kVA Of True On-Line Power
In A Compact 4U Package

Liebert GXT2 6 kVA is the first true on-line UPS that combines 6 kVA of power capacity, internal batteries and dual output

voltage in a single 4U size cabinet. This makes it an ideal fit in applications where the power requirements are demanding—but

rack space is limited. Designed for use in either rack or tower configurations, the new unit is well suited for installations such as

network closets or small computer rooms.

Modular Wiring And Bypass Capability

For installation flexibility, the Liebert GXT2 6 kVA
allows you to choose from several different wiring
configurations made possible by the use of removable
power distribution boxes that simply plug into the rear
of the UPS. The standard box provides terminal blocks
for hardwired input and output connections.

Controls and indicators

An optional hardwire version that includes a maintenance
bypass switch is also available. When the ease of plug­and-play power connections is desired, optional versions
of the power distribution box convert the Liebert GXT2
6 kVA to a cord-type input with receptacles for output
distribution, as well as maintenance bypass capability.

Patented Feature Enhances Reliability

The Liebert GXT2 6 kVA includes a patented output neutral

bonding feature designed to comply with UL 1778, which

requires that input conductors of the UPS (including

neutral) be disconnected from the input source when the

UPS is in battery mode. The Liebert GXT2 6 kVA features a

patented circuit that maintains the UPS output neutral to

ground bond in all modes of operation, thereby eliminating

any voltage induced on the UPS output neutral connection.

■

Built-in closure signals — Provides
notification to monitoring systems
of operating conditions including:
on battery, low battery, battery mode
shutdown and any mode shutdown.

■

Emergency Power Off (EPO) —
Terminal connections for a normally
open or normally closed emergency
power off switch.
