New Technology For A New Level
Of Performance
With over four decades of the most reliable
UPS systems, and the industry’s most experienced
engineering resources, Emerson Network Power has
delivered the Liebert
®
NXL™ UPS—the latest generation
of high availability, high performance UPS for critical
data center equipment.
Employs the latest generation insulated
gate bipolar transistors (IGBTs) and advanced inverter
logic with active harmonic control for enhanced
performance under a wide range of power conditions.
Provides high efficiency, up to 94%, but more
importantly, the efficiency is optimized with a very
flat efficiency curve that peaks at about 50% load
where most UPS systems, especially redundant UPS
systems, are operating. This results in significant
savings on the energy bill.
Digital control technology provides precise,
drift-free regulation of system operation.
Supports leading power factor loads up to 0.95
without derating, addressing the power needs of
current and future generations of computers.
The Liebert NXL UPS is Ideally Suited For:
Enterprise data centers
Co-location
Web Hosting
Government
Healthcare
Finance
Education
Insurance
Any other application requiring high levels
of power availability and computer-grade
power quality
Flexibility:
Matching battery and maintenance bypass cabinets for easy configuration.
Top or bottom cable entry.
Front access for installation and service.
Available in single-module and multi-module configurations with both single
and multi-bus distribution.
Easy, safe access for adding or changing monitoring cards without shutdown.
Higher Availability:
100% rated continuous duty bypass static switch—unfused.
Superior handling of present and future leading power factor
computer loads.
Short Circuit Withstand Rating (SCWR) withstand capability: 480V - 65kA,
100kA; 600V - 35kA, 65kA.
Color touch screen display improve user interface and reduce risk
of human error.
Built-in galvanic isolation provides proper grounding without
requiring a neutral.
Excellent dynamic performance.
Liebert ActiveStar
®
Digital Signal Processor (DSP) all digital controls.
Multi-module configurations provide for greater total capacity
and module redundancy.
Module level redundant components—fans and power supplies.
Generator and utility friendly with low input current distortion.
Highest documented MTBF > 5 million hours.
Lowest Total Cost Of Ownership:
Front access for installation and service.
Reduced installation and service time.
Internal bypass backfeed breaker avoids the complication of a device in the
distribution switchgear that must be controlled from the UPS but trip power
provided from a source energized when the bypass is deenergized.
Up to 98% efficiency when operating in Active Inverter Eco-Mode. Up to 94%
operating efficiency in dual conversion mode.
Optimized part-load efficiencies.
Improved cable access results in faster installation.
Built-in battery cabinet breaker isolates string for ease of service.
Battery cabinet with interconnecting bussing reduces site cabling.
