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.

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
