Emerson Network Power Introduces New Liebert® NXL UPS Models
New models provide an integrated solution, using higher “native” voltage to improve power system integration and ease of deployment.
Emerson Network Power has introduced the Liebert® NXL 400kVA, 575-600V on-line, maximum protection Uninterruptible Power Supply (UPS) system. The new system extends native 575-600V capabilities to power applications that require a high degree of resiliency. This UL listed UPS is now available in the U.S. and Canada to meet the needs of 575-600V applications.
This UPS expands the 575-600V applications in the Liebert NXL product family from 250-1100kVA.
“Today’s dynamic data centers require equally dynamic infrastructure solutions that are designed for continuous availability without impairing data center cost management,” said Peter Panfil, global vice president AC Power, Emerson Network Power. “The Liebert NXL 400kVA, 575-600V UPS provides data center professionals an optimized power solution that is quicker to install, highly efficient and cost-effective, while protecting their IT applications with the most reliable UPS system in the industry.”
For data centers that need to quickly scale to meet spiking power demands, the new system enables a faster, easier and more cost-effective deployment by using optimized internal transformers. This eliminates the need to install and wire separate external input and output transformers. In addition, the unit bypass is also 575-600V. This simplifies the use of an external maintenance bypass and a separately sourced bypass.
The Liebert NXL UPS is engineered to enable the highest levels of application availability. Its design allows operation at 100% load under a “stack up” of conditions that would require other systems to de-rate their output or compromise system availability. Simultaneous conditions such as clogged air filters, high ambient temperature, high altitude, fan failure, and low or high line conditions have been mitigated to ensure full rating at 100 percent operating loads. Like other Liebert NXL UPS models, it is available in single module and multi-module systems (1+N) to achieve redundancy and maximum reliability.
The Liebert NXL 400kVA, 575-600V UPS is also highly energy efficient. It offers higher operating efficiency compared to a transformerless UPS that requires external input and output transformers, while providing the added dependability and fault tolerance of a transformer based design. When operating in double conversion mode, the UPS delivers efficiency as high as 93.9%; when in Active Inverter Eco-Mode, it achieves efficiencies up to 97.6%.
For effective data center monitoring and management, Liebert NXL UPS battery cabinets are available with factory-integrated Alber® battery monitoring. This factory installed and tested system continuously monitors and diagnoses battery parameters. The reporting function keeps data center personnel informed of battery health and allows battery replacement at the right time, not prematurely or after a cell failure. Additionally, superior operational control can be realized through the Emerson Network Power data center infrastructure management system, the Trellis™ platform, or the Liebert SiteScan™ Web centralized monitoring and control system, each delivering improved overall control, visibility and infrastructure performance.
