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

The Liebert Nfinity UPS is available in scalable 4-16kVA and 12-20kVA models, 60Hz. Modules are scalable in 4kVA increments.
