Enterprise UPS
Business is accelerating. Needs and objectives are changing faster than ever. To help your data center keep
pace, the Liebert
®
eXL™ UPS facilitates rapid deployment through exible congurations and easy scalability.
Multiple Configurations to Fit Your Challenges
The Liebert eXL UPS offers both single module and multi-module configurations in a selection of kVA ratings, allowing
you to deploy the same technology in a variety of applications.
Single-module Configuration
Single-module Liebert eXL UPS configurations provide basic
protection with high levels of efficiency. The critical bus is
powered by a single Liebert eXL UPS system with bypass
capability. Large capacity modules can replace multiple
smaller modules in dual bus configurations, reducing
complexity and increasing reliability.
Multi-Module (1+N Parallel) Configuration
The Liebert eXL UPS can also provide multi-module operation
without the need for a system control cabinet. Multi-module
Liebert eXL UPS configurations utilize paralleling of single
units to offer easy scalability for capacity or redundancy. Each
unit has its own bypass static switch; bypass sharing is assured
through integral bypass load sharing inductors, which also
help simplify wiring and installation.
And, with a high input power factor and low input harmonics,
the Liebert eXL eliminates the need to oversize the generator.
Dual Bus or 2N
A dual bus system features two identical UPS systems and
supporting power systems, each capable of carrying the full
load. During normal operation the two systems support the
load. Each system may have redundancy built-in to maintain
redundancy while one system is offline.
Reserve or Catcher Bus
Creates a redundant overall system architecture, and can be
created with downstream power distribution similar to a dual
bus 2N architecture. This allows the UPS to operate at higher
utilization rates, while providing a highly fault tolerant power
system design.
Scalable Capacity to Keep Pace with Growth
Leveraging SoftScale technology, the Liebert eXL UPS can
seamlessly add capacity as your business needs expand—
without increasing physical footprint. This helps to avoid
unnecessary upfront capital outlays on extra capacity.
