PRODUCT OVERVIEW
An efficient uninterruptible power supply with scalable runtime
For the owners or operators of security systems, electrical installations, building management systems, IT rooms and the like, a reliable supply of electrical power is essential.
ABB?s new compact PowerValue 11/31 T UPS slots perfectly into this market segment. It incorporates all the features necessary to deliver reliable power, low running costs, long battery life, easy maintenance and full flexibility for the user.

Available in tower format, this UPS features double conversion, voltage and frequency independent (VFI) topology that protects against all supply failures. 10 and 20 kVA
versions are available ? and up to four units can be configured in parallel to boost power capability or provide redundancy. Three-phase or single-phase inputs can be accommodated and this choice is configurable in the field for maximum flexibility. Further, the PowerValue 11/31 T UPS can handle single or dual inputs ? allowing the customer to manage two independent power sources.
Simple to install and with a small footprint, the PowerValue
11/31 T produces stable, regulated, transient-free, pure sinewave AC power with extremely tight output voltage regulation.

Highlights:

Energy savings thanks to efficiencies up to 94% (online).
97% efficiency in ECO mode.
Low harmonic distortions (< 5% THDi) and active power?factor correction (0.99 input PF) eliminate interference?from other equipment in the network. Parallelling up to 4 units allows for increase of capacity?and introduction of redundancy to system to enhance?availability. Integrated manual bypass switch simplifies maintenance?and reduces need for external switchgears.?Can operate as frequency converter (50 Hz to/from 60 Hz). Compact solution that can achieve 5-16 min runtime?with internal batteries. Same model supports different wiring schemes: three-phase and single-phase input as well as single and dual input feed.
