3. Introduction
This is a Double Conversion true On-Line Uninterruptible Power Supply.
The double-conversion eliminates all mains power disturbances. A
rectifier converts the alternating current (AC) from the mains to direct
current (DC ). This DC 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.
The connected load is thus powered entirely by the UPS inverter voltage.
In the event of power failure, the maintenance-free batteries power the
inverter.
This manual covers the UPS listed as follows. Please confirm it is the
correct manual by checking the model number on the rear panel of the
UPS.
“B” Model: Internal battery
“C” Model: Internal charger for extended backup time
Model No.
