Vertiv Liebert Nfinity 12 Bay, 4kVA uninterruptible power supply (UPS) 2800 W

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.

- Scalable on-line UPS
- Allows user installation of hot-swappable replaceable modules
- Provides intelligent power, battery and control modules
- Offers internal bypass

Flexibility
- 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.

Higher Availability
- 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.

Lowest Total Cost of Ownership
- 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.

Ideally Suited For
