Product Overview

Liebert GXT RT+ DX UPS for Servers and Network Equipment

The Vertiv Liebert GXT RT+ DX UPS is a transformer-free online UPS range available in 1kVA, 2kVA and 3kVA capacities for small server rooms, workstations, network closets and communication systems.

True online double-conversion technology continuously converts incoming AC power through the rectifier and inverter before supplying connected equipment. This provides regulated output power even when utility voltage and frequency conditions fluctuate.

An IGBT-based rectifier and DSP control platform manage power conversion, voltage regulation, frequency regulation, battery charging, internal bypass and system protection functions.

The wide input-voltage and frequency range allows the UPS to continue operating from utility power during unstable mains conditions, reducing unnecessary battery discharge and helping preserve available battery runtime.

Input power-factor correction provides an input power factor of at least 0.99 at full load. Low input harmonic distortion helps improve compatibility with upstream electrical infrastructure and generator systems.

The user-friendly LCD panel displays UPS status, input and output voltage, load level, battery level, discharge time and fault information.

USB and RS-232 communication are available as standard, while optional SNMP connectivity enables browser-based and network-management monitoring.
