Vertiv Announces Dynamic Online Mode and New, Smaller Modules of High Power Density UPS Family

Vertiv announced a new feature for the Liebert EXL S1 line of uninterruptible power supply (UPS) systems, adding Dynamic Online mode, which allows operating efficiency of up to 99 percent. In addition, Vertiv introduced 500 and 600 kVA 400V module ratings for the Liebert EXL S1. The UPS family is available now in India in seven capacity ratings from 300 kVA to 1200 kVA, 400V. The UPS is also available in Asia Pacific, Europe and North America in a variety of input and output voltages. Dynamic Online mode is available for Liebert EXL S1 globally.

Vertiv introduced Dynamic Online mode to the Liebert EXL S1 to meet the needs of cloud, colocation and enterprise data centers that cannot sacrifice any level of availability for incremental gains in efficiency. With efficiency up to 99 percent, the Liebert EXL S1 operating in Dynamic Online mode offers substantial energy savings over legacy UPS systems which average 94 percent efficiency, and even improves on modern UPS systems that approach 97 percent efficiency. Over five years, a 1000 kVA Liebert EXL S1 can save more than $230,000 over a same-capacity 94 percent efficient UPS system and more than $140,000 over a same-capacity 97 percent efficient UPS system.

“In the fast-evolving Indian digital landscape, optimization, availability, and energy efficiency are critical elements of IT environments that support 24X7 businesses,” said Vikas Srivastava – director of product management for power, Vertiv in India. “The addition of high efficiency mode and extension of our Liebert EXL S1 UPS line allows our customers access to the best industry UPS systems, and highest levels of availability to their IT infrastructure.”

While in Dynamic Online mode, the Liebert EXL S1 inverter can instantaneously assume the load and maintain the output voltage well within the IEC 62040-3 Class 1 specification. That means systems equipped with Dynamic Online mode can safely transition from high-efficiency (Voltage Independent) mode to inverter mode with a near-zero-millisecond transfer, thus providing absolute load power protection under virtually any input power outage condition.

The new models of Liebert EXL S1 are up to 40 percent smaller than competitive systems and designed to meet the reliability and flexibility demands of the modern data center. Redundant DC variable speed fans enable the UPS to support 100 percent load even with multiple fan failures. Various input/output options add flexibility and reduce capital and installation costs. As with previously released Liebert EXL S1 modules, customers can parallel up to eight units and leverage Intelligent Parallel mode to automatically optimize efficiency at reduced load levels.

The system’s touchscreen interface offers a status-at-a-glance LED light bar, customizable views and multiple security options, while intelligent controls ensure seamless integration with multiple Vertiv and third-party building management and data center infrastructure management systems. All sizes of the Liebert EXL S1 UPS are available with lithium-ion batteries, flywheels, Albér battery monitoring, and LIFE Services.
