1 GXT5 DESCRIPTION
The Liebert® GXT5 is a compact, online uninterruptible power system (UPS) that continuously conditions
and regulates its output voltage. The Liebert® GXT5 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® GXT5 protects equipment from these disturbances. The Liebert® GXT5 continuously
charges its batteries from the utility power, enabling it to supply power to connected loads, even when the
mains fail.
1.1 UPS Features and Available Models
The GXT5 includes the following features. Table 1.1 below, lists the available models and power ratings.
•Enhanced load capacity with an output power factor of 1.
•Input power factor greater than 0.99
•Optional tower or rack installation to meet varying installation requirements.
•Adapts to areas with unstable power-mains supply via high-frequency double-conversion
topology structure, with high input-power factor, wide input-voltage range, and output
immune to grid interference.
•Full digital-control platform and hardware-design platform adapts to unstable mains supply
and load impact
•Programmable terminals with cascade protection protect key devices when load is heavy.
•Operation and display panel with model-specific color LCD offers simple configuration and
control of the UPS.
•ECO power-supply mode and smart-sleep mode help you save the maximum amount of energy.
