2. Operation
There are four basic operation modes for Protect 3.M 2.0 Series.
2-1 Normal Mode (Single Installation)
Fig. 2-1 Normal Mode (Single)
In normal mode, DC power rectified from AC input power charges batteries and
powers the inverter that transforms DC power to stable and clean AC power for
various loads. The “Double Conversion” technology allows regulating the utility to
provide pure and stable power to your precious equipment (Refer to Fig. 2-1).
2-2 Backup Mode (Single Installation)
Fig. 2-2 Backup Mode (Single)
When a power event (blackout, transient, surge, fluctuation…) occurs, the UPS will
automatically transfer from normal mode to backup mode. The battery will provide
emergency power to the inverter and then to the loads (Refer to Fig. 2-2).
