tornado eco plusA single-phase UPS with scalable runtime for critical applications
Quartino, Switzerland, June 24, 2014 – ABB, the leading power and automation technology group, has introduced its new PowerValue 31/11 T UPS series. PowerValue 31/11 T is a true double-conversion online uninterruptible power supply (UPS) that guarantees up to 20 kVA of clean, reliable power for critical single-phase applications. The online double conversion topology delivers power to the load even in the presence of severe disturbances in the utility.
ABB’s new compact PowerValue 31/11 T UPS 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 31/11 T UPS can handle single or dual inputs – allowing the customer to manage two independent power sources.The integrated manual bypass switch simplifies maintenance and reduces need for external switchgears. The high efficiencies reduce the power consumed by the installation and the low distortions and the active power factor correction lowers the interference from other equipments in the network.
Further, the PowerValue 31/11 T UPS can handle single or dual inputs – allowing the customer to manage two independent power sources. The product’s flexibility is also proven by its capability of working as a frequency converter. It transforms the input frequency from 50 to 60 Hz in the output or vice versa.
The compact solution offers different autonomy variations with inbuilt batteries or additional battery cabinets.With internal batteries the UPS can achieve 5-16 min runtime. Simple to install and with a small footprint, the PowerValue 31/11 T produces stable, regulated, transient-free, pure sine-wave AC power with extremely tight output voltage regulation.
