Vertiv has introduced the Vertiv Liebert APM2, a new energy efficient and scalable power solution to its uninterruptible power supply (UPS) systems portfolio.
The Liebert APM2 is compatible with lithium-ion (Li-ion) and VRLA batteries, and features a compact design that can scale from 30kW to 600kW in a single unit. It offers significant energy savings as compared to less efficient alternatives, and can also parallel with up to four matching units for additional capacity or redundancy. It is a CE certified UPS system available in 400V in Europe, the Middle East, Africa, Latin America, and Asia.
To satisfy the increasing power needs of edge computing applications, as well as the constrained space typical of these sites, it delivers a greater power output in a smaller footprint than similar capacity solutions, with the models requiring up to 45% less space than the predecessor UPS, Vertiv Liebert APM.
The Liebert APM2 operates with high energy efficiency in all modes, up to 97.5% in double-conversion mode; up to 98.8% efficiency when operating in dynamic online mode, which draws power through the bypass line and uses the inverter for balanced output and as an active filter; and up to 99% when operating in ECO mode, which takes advantage of stable grid input conditions to leverage the bypass line. All modes are automated based on user preferences.
The intelligent paralleling feature facilitates load sharing among multiple power modules, even across multiple units. This enables balanced unit runtime and offers automatic failover for enhanced system availability. Intelligent paralleling has also been shown to contribute to energy efficiency.
“Vertiv has introduced, in Liebert APM2 and other UPS systems, enhancements that improve operational efficiency and can contribute to a reduced data centre PUE, while also maintaining system availability,” says Giovanni Zanei, Senior Director, AC Power Global Offering and EMEA Business Leader at Vertiv. “In particular, the dynamic online feature, built on a robust global platform launched in 2018, enhances the already impressive UPS efficiency and has been adopted by energy and availability conscious customers, including many colocators.”
