Emerson Network Power has extended the capacity of the Liebert eXL family of large, transformer-free uninterruptible power supply (UPS) systems with the introduction of the Liebert® eXL 1200 kVA/kW UPS, as well as upgrades to the previously released 800 kVA/kW model. 

Ideal for colocation facilities and large enterprise data centers, the Liebert eXL UPS 1200 kVA is available in single module and 1+N (distributed bypass) multi-module systems, providing a choice of applications to best meet business needs. The Liebert UPS helps data centers maximize operational efficiency and increase PUE by delivering efficiency up to 97 percent in double conversion mode, with a potential savings of up to $12,000 per year over competitive technologies. Flexible configurations and capacity-on-demand with Softscale technology help data center managers conserve capital by enabling them to limit their initial investment, while allowing them to rapidly expand capacity.

“Large enterprise data centers and colocation facilities are looking for the most efficient UPS systems that can help them maximize efficiency, reduce operating expenses, improve PUE, achieve service level agreements and cost-effectively prepare for unpredictable future power requirements,” said David Sonner, vice president, marketing for Emerson Network Power in North America. “The Liebert eXL UPS enables today’s dynamic data centers to be rapidly deployed, flexible and easily scalable. It does this by offering high operating efficiency, smaller footprint, higher power density, optimal power delivery, scalable architecture and lower installation cost.”

Softscale technology allows the Liebert eXL UPS to provide capacity-on-demand,  initially sized to current power requirements and easily scaled to a larger capacity without adding footprint. The Liebert UPS can also parallel up to six units to increase capacity and redundancy. The unity power factor rating of the Liebert eXL UPS enables it to provide more usable power to address computing demand for modern IT loads, thereby eliminating the need to oversize the UPS. The larger capacity rating means that systems can be designed with fewer modules, reducing cost, complexity and possible points of failure.

The Liebert eXL UPS includes an integrated 10.4 inch color human machine interface (HMI) touchscreen which enables operators to see unit status at a glance, and provides detailed information making it easy to understand, diagnose and control the UPS. The system is enabled with Emerson’s LIFE Services with remote diagnostic and real-time communication, which allows for proactive maintenance and a condensed service cycle. This results in a decreased Mean Time to Repair (MTTR) and an improved Mean Time Between Failures (MTBF). It also has out-of-the-box compatibility with Emerson Network Power’s data center infrastructure management (DCIM) system, the Trellis platform, and is compatible with the Liebert Nform and Liebert SiteScan monitoring and reporting systems.

Since UPS battery failures continue to be the primary cause of unplanned outages, the  Liebert eXL UPS battery cabinets are available with factory installed and tested Alber® BDSUi battery monitoring systems, which continuously monitor battery health in order to provide advance warning of a pending battery failure, as well as enable maintenance and replacement based on the condition of the batteries rather than arbitrarily timed schedules.

The Liebert eXL UPS joins the previously introduced 800 kVA model and will be available in North America, Central America and South America for 480V, 60 Hz applications. The Liebert eXL UPS 1200 kVA SMS, 800 kVA 1+N,  and all Softscale models will be available to ship in January 2015, and the 1200 kVA 1+N system will be available to ship in March 2015.
