4. Introduction
ONLINE USV-Systeme AG is a leading manufacturer of Unin-
terruptible Power Supplies (UPS). The company, which is
based in Germany, has been developing, producing, distribut-
ing and providing support for UPS systems since 1988. In
terms of the sheer quantities sold, its products come top of the
German UPS market and have acquired an international repu-
tation thanks to their high level of quality and the excellent
support with which they are associated.
The ONLINE XANTO RT is an uninterruptible power supply
(UPS) based on double conversion technology (Classification
VFI-SS-111). It is the ideal form of protection for all business-
related data processing and telecommunications applications.
This means that power failures, voltage fluctuations and volt-
age surges, which can damage servers and other electronic
equipment, are prevented.
The double-converter principle eliminates all mains power
disturbances. A rectifier converts the alternating current from
the socket outlet (input voltage) into 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 power to the loads
(output voltage).
Computers and peripherals are thus powered entirely inde-
pendently of the input voltage. In the event of a power failure,
the maintenance-free batteries power the inverter. Because
the transition from mains to battery operation is gradual, the
switchover times that are inevitable with other systems can be
avoided.
Altering or modifying this appliance without the ex-
plicit approval of those officially responsible for en-
suring its proper operation could invalidate any war-
ranty claims.
