The Liebert Nfinity on-line UPS is a scalable system, designed with N+x parallel redundancy to provide a fault-tolerant network of power protection The Liebert Nfinity on-line UPS is a scalable system, designed with N+x parallel redundancy to provide a fault-tolerant network of power protection. The modular design of the Liebert Nfinity was devised to provide easy, user-installed upgrades as power demands grow. Configurations can be cost-effectively upgraded without re-investing in a new system or installation.

  • Allows addition of battery capacity without increasing footprint.
  • Extends backup time up to 72 hours with additional battery cabinets.
  • Upgrades for capacity or redundancy without the expense or installation downtime associated with the purchase of a new UPS.
  • Enables greater system control with remote management software.

  • Offers hot-swappable power, battery, control and display modules, allowing installation or replacement without compromising power to the load.
  • Provides redundant components at critical points of UPS operation.
  • Allows maintenance to be performed without shutdown.
  • Offers emergency power-off capability.
  • Transfers seamlessly to and from the bypass source, with patent pending intelligent bypass technology.
  • Operates with a wider input voltage window for fewer transfers to battery, saving battery wear and tear.
  • Provides compatibility with backup generator – handles frequency variations and other power fluctuations that occur during generator operation.
  • Sustains 110% of the system’s rated load for an extended period of time – the highest overload capability of any system in its class.
  • Ships as a complete, fully tested system, ready for final connection.
  • Reduces maintenance costs with modular batteries, controls and power components.
  • Allows scalability to cost effectively invest in added capacity as it is needed.
  • Ships with batteries connected and charged, reducing installation time and costs.

  • Small-to-medium-sized data centers
  • Network closets
  • VoIP
