Liebert EXS 20KVA
Compact design and improved performances
The new Liebert EXS is a monolithic transformer-free UPS which brings exceptional features for mission-critical applications. Its extraordinary double conversion efficiency up to 96.2% ensures remarkable operational cost savings, reducing both the Total Cost of Ownership (TCO) and the environmental impact.
At the same time, with its unity output power factor and high power density, Liebert EXS is able to provide the utmost active power possible in a compact footprint. In fact, its improved design reduces its footprint to a minimum, providing continuous power protection with optimized internal runtime in a standalone solution, making the Liebert EXS perfect for both IT installations and other mission critical applications, such as transportation, emergency lighting, healthcare, retail and government facilities.
Flexibility
To ensure superior protection for critical loads, the Liebert EXS range has been designed to optimize specific rating requirements, thus enhancing flexibility and installation space needs.
Liebert EXS’s flexibility is further enhanced through:
– Single and three phase output configurations up to 20 kVA
– Integrated parallel capability up to 4 units
– Common or distributed battery bank
– Internal and external battery configurations for optimized back up time management
– Casters for easy UPS repositioning
Output Configuration
Liebert EXS models up to 20 kVA can be configured on-site to deliver three (3/3) or single (3/1) phase output giving it the flexibility to adapt to changes in installation enviro
