Liebert PSI XR compensates for voltage variations
Emerson Network Power - Adaptive Power and Cooling
Liebert PSI XR
Emerson Network Power has introduced the Liebert PSI XR, a UPS characterised by high energy efficiency, a typical feature of the Line Interactive technology it is based on.
This characteristic is critical in IT environments, where maximising the use of power is vital.
In addition, Liebert PSI XR, with its 0.9 power factor, delivers a higher quantity of power with the same absorbed energy.
Liebert PSI XR features automatic voltage regulation (AVR), which compensates for voltage variations and avoids intensive use of batteries that would shorten their operating life.
For maximum installation flexibility, in rack or tower according to customer requirements, Liebert PSI XR is provided with an LED display that can be rotated by 90 degrees for easy reading independently of the selected layout.
Flexibility is also provided by a selection of communication ports: serial, USB, SNMP and contact closure, which cover a variety of installations.
The standard package includes the software for automatic operating-system shutdown, which offers additional data protection.
Available in 1000, 1500, 2200 and 3000VA ratings, the new UPS is designed to deliver maximum flexibility and high availability.
Besides a backup time among the longest in its class and hot-swap batteries that can be replaced by the user without disconnecting the load, Liebert PSI XR can extend the runtime of internal batteries by means of external battery cabinets.
Up to six cabinets can be added, with 2U compact size similar to the UPS, delivering an additional runtime of three hours at full load.
The standard warranty for Liebert PSI XR is two years with an optional one-year extension.
