Vertiv, formerly Emerson Network Power, designs, builds ,and
services mission critical technologies that enable vital
applications for data centers, communication networks, and
commercial & industrial environments.
Liebert EXL, the new generation of 80-NET UPS, delivers unsurpassed
performance to medium-large data centers as a result of proven
track record, successes, a reliable large installed base and more
than 10 years of acquired experience with the 80-NET technology.
Liebert EXL can operate with both standard VRLA and new Li-ion
batteries thus adapting to all possible requirements in terms of
runtime, life expectancy and TCO, and showing extreme flexibility.
Liebert® EXL features a transformer-free design with full IGBT
three-level double conversion technology, providing extraordinary
savings on installation and running costs, while at the same time
delivering first class load protection.
Maximized active power, high efficiency and complete compatibility
for modern, mission critical IT loads.
• Latest generation IGBT
• Adoption of a three-level NPC2 topology for both rectifier and
inverter
• DC controlled fan speed
• Intelligent paralleling mode
• Advanced digital technology and fast transfer
The seamless activation of Liebert EXL’s functioning modes ensures
the highest level of efficiency without compromising power quality
and availability.
Fast transfer technology ensures the quickest response time under
various conditions:
• Network fault (voltage variation, high/low impedance mains
failures)
• Load fault (short circuit downstream of the UPS)
• Type of load connected (PDU transformer)
The unit is able to discriminate between various types of
interferences and rapidly respond, while at the same time ensuring
compatibility with downstream equipment such as servers,
transformers, STS or mechanical loads.
Intelligent Paralleling
Liebert® EXL Intelligent Paralleling Feature
Activating the intelligent paralleling feature optimizes efficiency
at partial load, thus achieving superior running cost savings.
Enabling this feature allows the system to automatically adapt
capacity to meet immediate load requirements by switching excess
units to standby mode, while ensuring continued system
availability. Furthermore, the Intelligent Paralleling feature
allows each Liebert EXL unit to operate in standby mode for the
same amount of time, ensuring an equal life-span of module
components.
This intelligent paralleling feature further maximizes Liebert
EXL’s double conversion efficiency at partial load and allows for
an overall energy dissipation and TCO reduction.
Parallel Configurations
The Liebert® EXL can be connected with up to 8 units in parallel,
where single units can be serviced while the remaining units
continue to power the load. A Liebert EXL unit continues to operate
even while it’s being upgraded to a parallel system due to the
upgrade occurring via software settings. Furthermore, Liebert EXL
is backward compatible with the previous 80-NET generation, so as
to facilitate any legacy system power upgrade. Liebert EXL can
support both distributed and centralized parallel configurations
providing maximum energy saving via double conversion and
intelligent ECO mode, allowing to operate with a system efficiency
of up to 99%.
Distributed Parallel Configuration
Paralleling single Liebert EXL units offers advanced scalability.
In a distributed parallel configuration, each unit has a dedicated
static bypass switch, providing parallel operation without the need
for a system control cabinet, thus reducing initial installation
costs.
Centralized Parallel Configuration
With the Liebert EXL’s centralized parallel configuration, the
internal static bypass switch of each unit is disabled and an
external Main Static Switch.
(MSS) rated for the desired maximum capacity, is installed.
Therefore, the reserve supply to the loads operates via one central
piece of equipment (MSS).
The MSS can easily be integrated into any switchgear, thus
simplifying cabling and installation. System level commands are
given to the MSS via its integrated touch screen display.
User Interface and Advanced Diagnostic
Liebert® EXL makes your mission critical space a peaceful place
through its advanced diagnostic capability, measuring and logging,
enhanced event analysis as well as an intelligent colored
multi-language touch screen display.

Neutral Carbon Footprint
Liebert® EXL’s new generation architecture has been designed to
reduce energy and heat dissipation, consequently minimizing the
demand and consumption of air conditioning systems.
The combination of these factors, coupled with a double conversion
efficiency of up to 97%, reduces CO2 emissions to a minimum. This
contributes to ensuring that your customers’ data centers are a
step closer to meeting the industry’s environmental and efficiency
compliance standards.
Advanced control diagnostic, excellent operating efficiency,
intelligent paralleling feature, minimum footprint and high energy
density make Liebert EXL the perfect UPS to deliver secure power to
all mission critical applications, maximum energy saving and rapid
return on investment.
Liebert EXL provides system capacity from 300 kVA up to 9.6 MVA
which can be adapted according to diverse design requirements in
terms of flexibility, redundancy and system reliability.
Furthermore, its high power density in a minimum space allows
customers to maximize the number of racks and servers housed in
their data center, thus granting more space for IT equipment.
The Liebert EXL technology, has brought extraordinary benefits in
terms of:
- Zero impact on upstream infrastructure
- Perfect compatibility with modern mission critical loads
- Enhanced performances for maximum energy saving
- CO2 emission reduction
- Maximum system flexibility for all installations
- Reduced TCO
