Emerson Network Power increases capacity of Liebert NX UPS range

Thu, 11/15/2012 - 17:36 -- Ruth Williams

2-58bEmerson Network Power has added higher-capacity models to its transformer-less Liebert NX range of double conversion UPS systems.

The UL-listed Liebert NX 225-600 kVA is available for global regions with 480 V, 60 Hz applications, including North America, Central and South America, the Philippines, Taiwan and Korea. Emerson says the scalable UPS system offers mid-to–large-sized data centres a back-up power solution that provides the flexibility to grow incrementally without requiring infrastructure renovations.

Emerson’s proprietary Softscale technology allows the NX 225-600 kVA to be sized to current power requirements and 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 also offers IT managers, says the US firm, a cost-effective expansion path for data centre growth without adding to the UPS footprint.

The NX 225-600 kVA transformer-less UPS is rated at 95% efficiency in double-conversion mode during “typical 40%-80% load”. In eco-mode operation, the Liebert NX 225-600 kVA is up to 99% efficient.

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 centre. 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.
