Product Introduction
2 . Product Introduction
The
Liebert
GXT-MT
On-Line-Series
is
an
uninterruptible
power
supply
incorporating
double-conversion technology. It provides perfect protection specifically for Novell, Windows NT and
UNIX servers.
The double-conversion principle checks all mains power disturbances. A rectifier converts the
alternating current from the socket outlet to direct current. This direct current charges the batteries and
powers the inverter. On the basis of this DC voltage, the inverter generates a sinusoidal AC voltage,
which permanently supplies the loads.
Computers and peripherals are thus powered entirely by the inverter on the mains mode and in the
event of power failure, the maintenance-free batteries power the inverter.
This manual covers the UPS listed as follows. Please confirm whether it is the model you intend to
purchase by performing a visual inspection of the Model No. on the rear panel of the UPS.
