Emerson Network Power Announces New Input Configurations and Industry Certifications for Liebert® APM UPS

Columbus, Ohio – Emerson Network Power, a business of Emerson (NYSE:EMR) and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, today introduced 480-volt and 600-volt input configurations for its Liebert® APM row-based, modular uninterruptible power supply (UPS) system. In addition, all models of the Liebert APM are compliant with the Federal Trade Agreement Act (TAA), and UL 924 certified models are available to support emergency lighting requirements. The new voltage configurations and compliant models are now available across North America.


The Liebert APM is a transformer-free, on-line UPS that allows quick power capacity increases with the addition of internal FlexPower modular assemblies. The FlexPower modules allow the system to add capacity or redundancy in 15 kW increments up to 45 or 90 kW within a single cabinet without powering down connected equipment. The new input voltage capabilities are available on both 45 and 90 kW UPS configurations.


“The modular Liebert APM is an ideal solution for data center managers looking for the reliability to maintain business continuity and the flexibility needed to keep pace with increasing capacity needs,” said David Sonner, vice president power marketing, Emerson Network Power in North America. “The new input voltage configurations allow more applications to benefit from this flexible system. And these higher input voltages are accomplished without additional floor space in the 90 kW system.” The 45 kW system  includes the  transformer in the bypass distribution cabinet, without consuming additional data center floor space.”


Certain models of the Liebert APM are compliant with UL 924, meeting a variety of strict standards, including providing 90 minutes of backup time to support emergency lighting, and ensuring the manually operated interface is protected from accidental operation. The TAA meets requirements for most U.S. federal government procurements and contracts and is a requirement for any organizations receiving federal dollars.


The Liebert APM is available in two configurations. The 90 kW frame uses matching external battery cabinets for battery runtime, and allows for 90 kW of capacity, or 75 kW of capacity plus 15 kW of redundancy. The 45 kW frame allows for 45 kW of capacity, or 30 kW of capacity plus 15 kW of redundancy, and includes internal batteries with optional external battery cabinet for additional runtime. In both models, the external battery cabinet can be outfitted with an Alber® BDSi monitoring system to constantly monitor each battery, ensuring reliability and allowing for proactive management.


The UPS operates at up to 94 percent efficiency, with a virtually flat efficiency curve from 50-100 percent load, resulting in significant energy cost savings. It can be installed in raised or non-raised floor applications, and is ideally suited for small to medium-sized data centers, server rooms, production areas, labs and testing facilities, telecommunications and process controls centers.
