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.
