Vertiv, formerly Emerson Network Power, introduced the Liebert EXL S1, a large-scale uninterruptible power supply (UPS) system with a smaller physical footprint and the industry’s highest power density. The Liebert EXL S1 enables customers to optimize data center design space and allows for the deployment of additional revenue-generating equipment.
The Liebert EXL S1 is a 60hz, UL-listed UPS currently available in 1000, 1100 and 1200 kVA/kW capacities, with 600, 750 and 800 kW models following later this year. The Liebert EXL S1 is available in a distributed parallel configuration allowing users to parallel up to eight units for a total capacity of up to 9600 kW.
The system operates at 97 percent efficiency in double conversion mode and 99 percent in economization mode, and is compatible with lithium-ion batteries. Configuring for single or dual input/output is made by a common source connection cabinet that includes jumpers to enable either single or dual sources while minimizing space.
Additionally, OSHA safety approved access is provided for control wiring and communication inputs and outputs at the top of the unit. Each of these features also enable less costly installation.
According to Peter Panfil, vice president, global power for Vertiv: “The Liebert EXL S1 delivers on reliability and agility with configurations that address the critical needs for cloud, colocation and progressive enterprise environments – where the emphasis is on capital efficiency and reducing operating costs while enabling rapid deployment.”
The Liebert EXL S1 is seismic certified (CBC, IBC 2015, ASCE 7-05) and has high-impedence DC ground fault detection for 2014 NEC compliance. It has a transformer-free, three-level insulated-gate bipolar transistor (IGBT) on both the rectifier and inverter. The system’s dual simultaneous communications protocols provide compatibility with multiple data center infrastructure management, IT monitoring and building management systems.
