ABB’s design, technology and quality experience in high-end UPS engineering has been applied to design these UPSs that offer full protection and complete peace of mind by ensuring the connected equipment always sees a clean, regulated and reliable voltage.

Both UPSs share many features: As well as intervening within 2 to 6 ms to provide power when the mains is lost, they also filter out input power disturbances such as surges, line noise or harmonics. If the input power factor starts to play up, advanced protection software will automatically correct it. A plug-and-play approach and an intuitive LCD interface make operation simple. The easy-to-replace, internal enhanced-runtime batteries are designed to give stable, low-maintenance performance over many years of service. A comprehensive battery management suite and fan cooling ensure batteries are not overloaded and that they do not overcharge, discharge too deeply or overheat.

An integrated cold-start feature allows the UPSs to start up by themselves – when needed. Both the PowerValue 11LI Up and PowerValue 11LI Pro are available in models that span the 600 to 2,000 VA range.

Intended for users with lower power requirements, the line-interactive PowerValue 11LI Up is the ideal UPS for modest IT applications. On the other hand the PowerValue 11LI Pro is the perfect candidate for entry-level network applications – such as server rooms in offices, network cabinets, workstation clusters, domestic networks, point-of-sale, network-attached data storage arrays and similar-sized situations.
