Liebert NXL 750 kVA Single And Multi-Module
UPS Systems
The Liebert NXL 750 kVA is a high capacity, three-phase UPS
solution with advanced technologies that improve performance,
reduce energy costs and lower total cost of ownership.
Much More Power In A Lot Less Space
The Liebert NXL 750 kVA UPS features a small footprint compared to
older three-phase models and features compact maintenance
bypass and battery cabinets that require less floor space. It also
features better cable access to speed installation.
The Liebert NXL 750 kVA utilizes the very latest IGBT and digital
control technology. These improvements contribute significantly to
a smaller footprint and more efficient operation without sacrificing
the high levels of reliability. The UPS supports leading power factor
loads up to 0.95 without derating, addressing the power needs of
this generation and future generations of computers. The Liebert
NXL 750 kVA has a 94% operating efficiency and features a wider
input voltage to reduce the number of charge and discharge cycles.
Multi-Module Configuration
The need for maximum reliability has driven
customers to add redundant UPS modules to their
critical power systems. First, a redundant UPS
module improves maintainability since one UPS
module at a time can be taken off-line for service
without shutting down the whole system. Second,
a redundant UPS module adds fault management
capability by preventing a single module or single
battery failure from taking down the critical
output bus.
The Liebert NXL 750 kVA multi-module
configuration provides redundant capability or
increased capacity utilizing a specially designed
system control cabinet. Up to eight units can be
used together in a multi-module system.
