Figure 1: Block Diagram of the UPS's Operation

In case of a power failure, the UPS provides backup power for a specific period.
The system is user friendly. Its operation is simple and requires no previous technical
knowledge. The UPS operates on-line and, once activated, provides voltages of
3×208Vac at a stabilized 50 or 60 Hz frequency—depending upon your
configuration—to load.
When backup service is provided (upon mains power failure), the UPS is powered by
batteries and maintains a constant output voltage supply. The system informs the
operator, by means of LED indicators and audible signals, when a power failure
occurs.
The UPS is equipped with a Static Switch (ST/SW) that enables the load(s) device(s)
to continue normal operation when the inverter is unable to supply exceptionally
heavy loads, such as during power surges, or in case of inverter failure—for any
reason.
An LCD display on the UPS front panel provides complete, real time information
reflecting the UPS's operational status.
