Emerson PSI-XR manual Flexibility, Configurable input voltage window

Reliable UPS Protection And Extended Battery Time To Keep Your Network Up And Running

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 or 30 Amp receptacles.

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.

Rack Rail Kit

These telescoping rails mount to the sides of the UPS to facilitate installation into a rackmount enclosure.
