4. OPERATING PRINCIPLE
•
Line-interactive UPS’s provide perfect protection of PCs and peripherals. If there are drops of
power supply in the mains, the device connected to the UPS is powered by battery via inverter
converting +12/24 V DC voltage into 220 V AC voltage, which allows to save data and shut down the
operation of the system properly.
•
If mains voltage is normal, the current goes through a
fi
lter to AVR module (Automatic Voltage
Regulator). Voltage is increased or reduced if necessary to correspond to standard 220 V voltage,
then voltage is supplied to the device connected to the UPS. At the same time the charging unit
charges the battery.
