3.1 On-Line Mode
In On-Line mode, the main AC source supplies AC power via the Input Switch (Q1) to the
rectifier, and the rectifier converts the AC power to DC power and supplies the DC power to
the inverter. In the meantime, the rectifier provides charging power to the batteries. After
receiving the DC power, the inverter converts it into clean and stable AC power to the
connected critical loads via the Output Switch (Q4). During On-Line mode, the UPS’s tri-
color LED illuminates green and the text ‘
On-Line
’ appears in the upper right corner of the
LCD screen.
