2 PRODUCT DESCRIPTION
The Liebert GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions
and regulates its output voltage. The Liebert GXT4 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 GXT4 protects equipment from these disturbances. The Liebert GXT4 continuously charges
its batteries from the mains, enabling it to supply power to connected loads, even when the mains fail.
