Columbus, Ohio – Emerson Network Power, a business of Emerson (NYSE:EMR) 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 today’s 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.


The scalable UPS system offers mid-to–large-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.


“IT and facility managers are continually dealing with rapid and unpredictable compute growth, while being forced to work within limited budgets and a fixed floor space,” said Peter Panfil, vice president of global power, Emerson Network Power. “The Liebert NX 225-600 kVA is a solid investment that helps prepare data center managers for what’s next while providing an economical growth path for tomorrow’s computing needs. It provides high efficiency in both normal and Intelligent EcoMode operation—and superior reliability and availability needed to meet growing demand.”


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® software interface. Data also may be directly output to a network for integration with other monitoring systems, including building management systems.


The Liebert NX features optional matching battery cabinets that can be equipped with Alber® BDSi integrated battery monitoring to proactively monitor battery health, allowing proactive battery replacement and optimized availability.


To further ensure the health of the system, the Liebert NX 225-600 kVA UPS can be remotely monitored through Life.net, and the Emerson Network Power Liebert Services 24/7 service center. This service provides pre-emptive notification of more than 150 operating parameters, immediate identification of problems and a detailed reporting of power and equipment trends. Life.net monitoring is provided standard for the first year of operation.
