3. Introduction
This On-Line-Series is an uninterruptible power supply incorporating
double-converter technology. It provides perfect protection specifically
for Novell, Windows NT and UNIX servers.
The double-converter principle eliminates 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 periphery are thus powered entirely by the mains
voltage. In the event of power failure, the maintenance-free batteries
power the inverter.
