More Ways To Achieve The Level Of Protection And Reliability You Need

With unity power rating - 1100kVA / 1100kW - Liebert NXL UPS has the highest capacity of any monolithic UPS in the industry. The result is real savings versus installing multiple smaller units to achieve capacity with a reduction in requirements for floorspace, maintenance and installation costs. In addition, the UPS is available in multi-module configurations for Tier levels 2, 3 and 4, ensuring the right level of power redundancy for any critical application.

Single-Module Configuration

Single-module systems provide a basic protection configuration. The critical bus is powered by a single UPS system with bypass capability.

Multi Module Configurations

Liebert NXL UPS 1100kVA units can be paralleled to obtain higher total capacity or to obtain redundancy. Many facilities have added redundant UPS modules to their critical power systems, to meet the need for maximum reliability. A redundant UPS system adds fault management capability by preventing a single module or single battery failure from taking down the critical output bus. Use of redundant UPS modules also improves maintainability since one UPS module at a time can be taken off-line for service without shutting down the whole system.

Flexibility:

• Available in single-module and multimodule configurations with both single and multi-bus distribution y Bypass withstand rating achieved without fuses to allow coordination with downstream feeder circuit breakers y Multiple voltages and grounding configurations available y Compatible with switch mode and traditional power supplies and rated 1000kW for a 0.95 leading power factor load y Liebert® IntelliSlot® communication cards for site monitoring and management

Monitoring And Control Capabilities That Keep You Informed And In Charge

Integrated Control And Monitoring Main Display Screen

Liebert NXL UPS has a large, color touchscreen display that leads the user through logical menu sequences to view needed information. The color, backlit, micro-processor based display is autonomous of the system control logic. The simple menu-driven system virtually eliminates the possibility for human error. The large touch screen display can be set to show a system one-line diagram or mimic panel. It can also display advanced metering information, alarms, configuration or start-up/shutdown/transfer information.

• Quickly check operational status.
• Monitor power flow through UPS along with all meter readings.
• Menu-driven operator procedures to ensure safe operation.
• Check status reports and history files.
• Adjustment of programmable parameters. Password is needed for both operations and adjustments.

When the UPS goes into battery mode, it is vital to ensure that your batteries have enough life to run the system until the generators are available. The Liebert NXL UPS has the ability to monitor the expected run time of the batteries and provide alarms.

Battery Cycle Monitor

The Liebert NXL UPS system firmware collects and retains information on the last 132 events that involved discharging the UPS battery. The battery discharges are categorized by discharge duration, and crucial event details are stored, providing onscreen access to information that affects battery health. Summary information on the total number of events, cumulative ampere hours and the total discharge time since a given date is also stored and available for review. All information may also be collected remotely through the Remote Service Terminal application program.

Liebert IntelliSlot Unity Card Communications Interface Card

The Liebert IntelliSlot Unity communications platform is the next generation of communications interface enhancing the enablement of Vertiv software tools and services, including Trellis, Liebert Nform, and LIFE Services, as well as third-party customer protocols for Vertiv equipment.
