Liebert NX UPS: 10-30 kVA
Power designed to grow with your needs.
The Liebert NX 10-30 kVA product family offers true on-
line, double conversion, three-phase UPS systems that
deliver complete, centralized power protection for
mission-critical systems. Available in 10, 15, 20 & 30 kVA
capacities, these rugged units are designed to meet the
high availability power needs of a wide variety of IT
applications. Liebert NX 10-30 kVA UPS systems
combine advanced operating features, compact size and
low cost of ownership in a range of sizes to suit room or
data center needs.
The “all-in-one” design of the Liebert NX 10-30 kVA UPS
provides more protection security and efficiency than
using separate, smaller power units spread throughout
the facility. The Liebert NX delivers complete protection
with a true on-line IGBT-based double conversion design.
The system’s advanced topology features a digital signal
processor controlled IGBT rectifier and IGBT inverter.
