Liebert® EXS from 10 to 80 kW

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 environments.

Integrated Autonomy (10-60kVA)

Liebert EXS provides an optimized integrated autonomy which results in back up times in a compact footprint.

Its internal architecture is able to house up to four battery strings, further optimizing integrated autonomy and delivering the added advantage of virtually eliminating the need for an external battery cabinet. This furthermore reduces installation costs and minimizes the demand on physical space. In addition, Liebert EXS's powerful battery charger ensures rapid recharge, increasing its ability to manage longer back up times.

Full Galvanic Isolation

Liebert EXS offers integrated full galvanic isolation, meaning that an isolation transformer may be housed inside the UPS cabinet. This greatly reduces the system footprint, thus providing space saving advantages. The transformer may be connected to the input or to the output of the UPS, providing:

Full galvanic isolation for medical and other critical applications
Installation with two independent input sources (with different neutrals)
Installation in distribution without neutral

In The Field

Parallel Ready

Liebert EXS can be connected with up to four units in parallel. A single unit can be upgraded to parallel operation via easy to modify software settings, allowing the system to be customized for the requested configuration. The loop parallel connection used in paralleling the system delivers ultimate reliability and eliminates the possibility of a single point of failure, ensuring perfect load sharing and fast detection of any variation in the system status.
