The Liebert

®

 GXT3

™

 is a compact, online uninterruptible power system (UPS) that continuously 

conditions and regulates its output voltage. The Liebert GXT3 is designed to supply microcomputers 

and other sensitive equipment with clean sine wave input power.
Upon generation, AC power is clean and stable. However, during transmission and distribution it is 

subject to voltage sags, spikes and complete failure that may interrupt computer operations, cause 

data loss and damage equipment.
The Liebert GXT3 protects equipment from these disturbances. The Liebert GXT3 continuously 

charges its batteries from utility power, enabling it to supply power to connected loads, even when 

utility power fails.
This sections describes the UPS, its features, models, appearance and components, operating 

principles and operating mode.

• Intelligent battery management to extend the battery life
• Operation and display panel with LED for monitoring load percentage and battery capacity inde-

pendently

• Flexible network management with Liebert MultiLink

™

 software

• Fan fault self-inspection and automated diagnostic function
• Intelligent fan operation, automatically changing rotation speed depending on system require-

ments, to decrease power consumption and noise

• Input circuit breaker to ease recovery from overloads
• Safety approval from UL and cUL
• Communication options: USB port, Liebert IntelliSlot

®

 port and terminal block communication

• Dry contacts for remote monitoring
• Input power factor greater than 0.99
• Output voltage selection function

Eight UPS models are available.
