Reliable UPS Protection And Extended Battery Time 
To Keep Your Network Up And Running
2
The flexible design of Liebert PSI-XR  allows the unit  
to be configured as a self-standing tower or to be 
rack-mounted within a 2U space. It is available in  
four capacities, and both 120V or 230V models.
The UPS features an innovative line-interactive design incorporating  
buck/boost automatic voltage regulation technology. This protects against 
utility voltage fluctuation by raising and lowering utility power to the level 
needed by the connected equipment. It also allows the UPS to prolong  
battery life by maximizing its time on utility power before going to battery.

Liebert PSI-XR Standard Features:
Flexibility:
Six to seven battery-backed outlets
Allows the Liebert PSI-XR to be more flexible in accommodating 
additional equipment to be connected to the UPS via the 15, 20

Configurable input voltage window
Allows the UPS to be properly matched to the incoming utility 
power and adjusts its input window and transfer points to  
supply precisely regulated power to connected loads within the 
selected range. Also enables the UPS to meet the required input 
voltage when transferring to battery.        
Rotatable Display Panel
90 degrees rotatable LED display  
panel rotates 90° to make the readout  
of the LED display easy to see in rack  
or tower position.
Automatic Frequency Sensing
The UPS automatically adjusts to the input frequency,  
50Hz or 60Hz.
