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.

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.

LiebertDelivers 6 kVA Of TrueOn-Line PowerIn 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.

An optional hardwire version that includes a maintenance bypass switch is also available. When the ease of plug- and-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.

Other Product Features Of The New Liebert GXT2 6 kVA Include:

Flexibility:

■Rack/tower configuration —

A single part number installs in either configuration.

■Automatic frequency detection —

The Liebert GXT2 6 kVA detects and matches line input frequencies of either 60 or 50 Hz.

■Additional runtime with 2U battery cabinets — UPS cabinet includes rear panel plug-and-play connections for optional additional battery cabinets.

■IntelliSlot™ communications port —

Utilizes Liebert IntelliSlot Web Card to provide SNMP and web-based monitoring and control your UPS.

■Includes Windows-based configuration program — Allows various operating parameters to be adjusted and tests to be scheduled.

■Built-in serial communications for use with Liebert MultiLink™ Automated Shutdown Software — Allows you to monitor communication between the

UPS and a server, and ensures

a graceful unattended shutdown.

■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.

Reliability

■Wider Input Voltage Window Minimizes Battery Use — The Liebert GXT2 6 kVA features a wide input voltage window that allows the UPS to support the critical load without having to transfer to battery, extending system availability for when battery back-up is truly needed.

■Internal automatic and manual bypass — Assures continuity of power to critical loads during system maintenance or in case of internal fault.

■Self-diagnostics — Automatically tests unit electronics and batteries. Designed to simplify maintenance and troubleshooting.

■User-replaceable hot-swappable internal batteries — Provide five minutes of runtime at full load.

Low Total Cost Of Ownership

■Standard two-year warranty

■Uses less rack space leaving more room for network equipment.

■Batteries are shielded from heat generating electronic components, enhancing battery life.

■Battery cutoff voltage automatically adjusts based on load, extending battery life by preventing over-discharge of batteries.

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.
