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 in-
verter converting +12/24V DC voltage into 220 V AC voltage, which allows to save data and shut
down the operation of the system properly.
• Voltage mains supply goes through a lter to AVR module (Automatic Voltage Regulator). Volt-
age is increased or reduced if necessary to correspond to standard 220 V voltage, then voltag
issupplied to the connected equipment. At the same time the charging unit charges the battery.
