1.4OPERATION OVERVIEW

The UPS provides two power paths between the utility source and the critical load. Figure 1.1 shows the path for normal operation, with the load powered by the inverter.

Figure 1.2 shows the path for bypass operation, with the load supplied through the static bypass line.

A)Normal operation: Load power supplied by each system UPS inverter.

During normal operation, the path through the UPS inverter is used to power the load.

In Figure 1.1 input AC power is converted to DC by the Converter. DC power is utilized to charge the UPS battery and to provide power to the Inverter. The Inverter converts the DC power to clean AC power to supply the critical load.

The conversion - inversion process eliminates any voltage transients or fluctuations existing in the input power before it reaches the critical load.

The power drawn by the critical load is equally shared between all UPS systems when multiple UPSs are in Parallel Operation. (Refer to Figure 3.6 that shows a sample of Parallel Operation System Configuration.)
