3. Introduction
This on-line UPS
incorporates the latest in double-conversion topology, which
provides perfect protection for your critical and power supply sensitive
equipment specially Novell, Windows NT and Unix servers.
The double-conversion principle eliminates all the mains power disturbances.
Here, a rectifier converts the alternating current of the mains supply to direct
current. This direct current charges the batteries and powers the inverter. The
inverter, in its turn, generates a sinusoidal AC voltage, which permanently
supplies the loads with uninterrupted, clean and sine-wave voltage.
Computers and peripherals are thus powered entirely by the inverter. In the
event of mains power failure, the maintenance-free batteries supply the
inverter.
This series of UPS units are produced in three power ratings 1kVA, 2kVA and
3kVA with standard battery backup time and with extended battery backup
time, as shown in the table below.
