Three-Phase Online UPS for Mission-Critical Equipment
Vertiv Liebert GXTMT+ LX UPS
is a 10kVA / 9kW online UPS with three-phase
input and three-phase output for demanding
power-protection applications.
True Online double-conversion architecture
processes incoming power through the rectifier,
DC stage and inverter before delivering
conditioned AC power to connected equipment.
DSP-based control manages power-conversion
functions and contributes to accurate output
regulation and responsive operation.
Active power-factor correction operates across
all input phases, with an input power factor of
0.99 under specified operating conditions.
The UPS has a rated output power factor of 0.9,
allowing its 10kVA rating to provide up to
9kW of active power.
A wide 305–520Vac three-phase input window
helps the UPS accommodate substantial utility
voltage variation.
Frequency-converter operation, ECO mode,
generator compatibility and emergency
power-off provide additional operating
flexibility.
Integrated static and maintenance bypass,
communication interfaces and a scalable power
architecture make the platform suitable for
critical equipment requiring dependable
three-phase power protection.
