2 GXT4 DESCRIPTION
The Liebert® GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions
and regulates its output voltage. The Liebert® GXT4 supplies 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 utility power, enabling it to supply power to connected loads, even when the
mains fail.
