3. Introduction
This Online Series is an uninterruptible power supply incorporating double-conversion
technology. It provides perfect protection specifically for computer equipment,
communication systems to computerized instruments.
It
s true online double-conversion design eliminates all mains power disturbances. A
rectifier converts the alternating current from the utility power to direct current. This
direct current powers the inverter. On the basis of this DC voltage, the inverter
generates a pure sinusoidal AC voltage, which is constantly powering the loads.
Computers and Peripherals are thus powered entirely by the UPS. 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.
