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.
