Liebert NX (10-30kVA)

Liebert NX is a mid-sized, three-phase uninterruptible power supply (UPS) system that delivers complete, centralized data center power protection. Designed to meet the high availability power needs of a wide variety of IT applications and equipment, the UPS combines compact size, advanced operating features and low cost of ownership. The 120/208-Volt, three-phase version of the Liebert NX is available in four sizes including 10kVA, 15kVA, 20kVA and 30kVA capacities.

Features

Flexibility

Power communications available through a Relay Contact Card, OpenCommsâ„¢ Web Card and MultiLinkâ„¢ shutdown software.
Ultra-quiet performance with noise levels below 54dB allows greater latitude in where to place the unit.
Large and user-friendly LCD display provides operating information in twelve languages.
Up to three Liebert NX modules can be paralleled and a fourth added for redundancy without using a centralized controller or centralized static switch.
For safe and convenient servicing of the UPS, the unit includes a built-in maintenance bypass. Optional wrap-around maintenance bypass is also available.
Easy servicing due to front accessibility of critical components, self-diagnostics and various monitoring options.

Higher Availability

True on-line double conversion technology corrects all types of power fluctuations.
Advanced inverter control technology provides the highest output power quality.
Redundant power supply cords, redundant cooling fans and highly efficient cooling of critical components.
Minimized transfer to battery, reducing the number of charging and discharging cycles, due to the wider input voltage window of +10 to -20% and a frequency tolerance of 40Hz to 72Hz.
Compatibility with dual bus synchronization system enables you to transfer the load to an alternate power source for maintenance activities.
High overload protection handles 125% for 10 minutes, 150% for one minute and a 1000% overload for 10 milliseconds.
An intelligent battery management algorithm monitors the battery to detect any premature battery failure.

Lowest Total Cost Of Ownership

Temperature-compensated battery charging extends battery life.
Highest possible input power factor for maximum efficiency.
Adjustable power walk-in from 5 seconds to 30 seconds, along with reduced input current distortion and power factor correction, also enables you to save money by reducing back-up generator sizing requirements.
The unit's compact footprint requires less floor space, leaving you with more room for other equipment.

Ideally Suited For

Server rooms and mid-sized data centers
Network components including critical routers and switches
Networks (LAN and WAN)
Industrial process and motion automation for mid-sized plants
Medical diagnostic/imaging equipment
