The Liebert NXL 1100kVA/1100 kW UPS is from Emerson Network Power.
Emerson Network Power has introduced the Liebert NXL 1100 kVA/1100 kW 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 applications—480, 575, or 600 Vac. The Liebert NXL UPS is the first large transformer-based UPS system to be tested, UL listed, and labeled to UL1778 fourth edition specifications. The highest-capacity transformer-based UPS in the industry, Liebert NXL 1100 kVA/1100 kW UPS provides operating efficiency at typical load levels in double conversion mode with up to 98% 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.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
