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.
