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.
