UPS from Vertiv
The Liebert® EXL S1 addresses customer needs for more power in a smaller space.
Vertiv’s Liebert® EXL S1 is a large-scale uninterruptible power supply (UPS) system with a significantly 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 60 hz, 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% efficiency in double conversion mode and 99% in economization mode, and is compatible with lithium-ion batteries.
Configuring for single or dual input/output is made easy by a common source connection cabinet that includes well placed jumpers to enable either single or dual sources while minimizing space. Additionally, convenient and 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 easier, faster, and less costly installation.
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.
