High-Efficiency Power Protection: Emerson Network Power Introduces Liebert NXL 1100 kVA/1100kW to Provide High-Efficiency UPS Protection for Critical Data Centers

Columbus, OH (PRWEB) April 12, 2012

Summary: Emerson Network Power, a business of Emerson and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, today introduced the Liebert NXL 1100kVA/1100kW UPS to offer medium to large data centers a level of operating efficiency previously available only in transformer-free systems, but with the safety, fault tolerance, and reliability demonstrated by transformer-based systems. The Liebert NXL UPS is UL and CSA listed and is available globally for 60 Hz applications480, 575 or 600VAC.

Details: The Liebert NXL UPS is the first large transformer-based UPS system to be tested and UL listed and labeled to UL1778 fourth edition specifications. The highest-capacity transformer-based UPS in the industry, Liebert NXL 1100kVA/1100kW UPS provides the industrys best operating efficiency at typical load levels in double conversion mode with up to 98 percent efficiency when operating in Intelligent Eco-Mode.

The Liebert NXL UPS battery ground fault isolation results in normal system operation even under battery ground fault conditions. During these fault conditions, the system does not go to bypass as happens with transformer-free technologies. The Liebert NXL UPS is available in many configurations, including single module, 1+N distributed bypass and N+1 central bypass, to ensure the right level of power redundancy for any critical application and Tier level. The robust design of the Liebert NXL UPS allows operation at 100 percent load under a stack-up of conditions that would require other systems to de-rate their output or compromise system availability.

The Liebert NXL UPS features optional matching battery cabinets that can be equipped with Alber BDSi integrated battery monitoring to proactively monitor battery health. A Liebert NXL System Control Cabinet is available for N+1 parallel configurations, controlling the operation of the system and also containing the system static bypass switch.

Liebert SiteScan Web centralized monitoring software can be used to offer maximum control, monitoring and visibility to Liebert NXL UPS. It also comes with the ability to output data directly to a network for integration with other monitoring systems.

Quotes attributable to Peter Panfil, vice president of global power, Emerson Network Power:

As critical power requirements in todays high-availability data centers continue to increase, IT and facility managers are seeking the greater power capacity and superior reliability and energy efficiency needed to meet growing demand. Until recently this has been fueling a growing interest in using transformer-free UPS modules in three-phase critical power applications.

The transformer-based Liebert NXL 1100 kVA UPS utilizes the latest power protection technology to offer a level of operating efficiency that was previously only available in transformer-free systems.

It also features battery ground fault isolation that ensures normal operation under battery ground fault conditions and isolates personnel working on the DC systems from hazardous AC voltage.

Emerson Network Power Increases Capacity of Liebert NX UPS Product Line with introduction of 225 kVA 600 kVA Ratings

Columbus, OH (PRWEB) June 27, 2012

Emerson Network Power, a business of Emerson and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, has added new, higher-capacity models to the transformer-free Liebert NX family of double conversion UPS systems with todays release of the Liebert NX 225-600 kVA UPS. The UL-listed Liebert NX 225-600 kVA is available for global regions with 480V, 60 Hz applications, including North America, Central and South America, the Philippines, Taiwan and Korea.

Highly Efficient, Scalable UPS with More Real Power

The scalable UPS system offers mid-tolarge-sized data centers a backup power solution that provides the flexibility to grow incrementally without requiring infrastructure renovations. Softscale technology allows the Liebert NX 225-600 kVA to be sized to current power requirements and easily scaled up to a larger capacity with a simple software key, which is a more reliable method than adding hardware to grow the module rating. It offers IT managers an economical expansion path for data center growth without adding to the UPS footprint.

The Liebert NX 225-600 kVA transformer-free UPS operates at extremely high efficiency, resulting in lower utility costs. In normal, double-conversion mode, the Liebert UPS operates at 95 percent or higher efficiency during typical 40 percent – 80 percent loading. During Intelligent Eco-mode operation, the Liebert NX 225-600 kVA UPS operates at efficiencies up to 99 percent. This high efficiency operating mode is standard on each system and enables the unit to run on bypass power during customer-defined conditions. This no-break mode is optimized for the Liebert NX design by maintaining power to the rectifier, and keeping the inverter energized and synchronized with the input for fast, no-break return to full double-conversion mode.

Monitoring Capabilities Keep Data Center Managers Informed and in Control

The Liebert UPS features a real-time, menu-driven touch-screen display panel that monitors a variety of operating parameters, including unit metering and status information. The Liebert NX also can be centrally-monitored and managed through an optional Liebert SiteScan
