The Vertiv™ Liebert® EXL S1 UPS is available in 250-1200 kVA ratings and is optimized for maximum efficiency and power density. It offers the smallest footprint available for its kVA size range and is up to 60% smaller than some competitors. It is also significantly smaller than similar class UPS systems. For the conscientious buyer who needs every square foot to offer a positive ROI, such as for colocation providers, hosting and cloud businesses, the Liebert® EXL S1 UPS allows customers to either redeploy the saved space to implement more revenue generating IT equipment or reduce the actual design size of their equipment rooms, thus saving construction costs. Plus, the new Dynamic Online mode enables operating efficiency up to 99% without sacrificing availability. While in this mode, the inverter can instantaneously assume the load and maintain the output voltage within the IEC 62040 Class 1 specification, thus offering the same level of availability typically achieved in a double conversion operating mode. The new touchscreen control panel ensures Status At A Glance convenience, flexible views and multiple security options. Intelligent controls and communications integrate with Liebert® Nform, Liebert® SiteScan™ and the Liebert® Trellis™ Platform as well as 3rd party BMS and DCIM systems. LIFE™ Services provides 24x7 remote monitoring by our expert staff to improve availability and lower labor costs. The Liebert® EXL S1 UPS is fully compatible with the lithium ion battery solutions offered by Vertiv.
