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.
