4.4.1 Normal operation
During normal operation, the single-phase AC input voltage feed the
load through the AVR. At the same time, it provides the battery
charging.
4.4.2 Bypass operation
The load switches to bypass automatically, in the event of a failure of
the UPS. In this mode, the load is powered directly from the mains and
in case of a mains failure, the power supply to the load may be
interrupted.
4.4.3 Battery operation
In case of power failure, the battery feeds the load without
interruption. The battery voltage drops based on the amplitude of the
discharging current. The voltage drop has no effect on the output
voltage, which is kept constant by changing the PWM modulation. An
alarm is activated when the battery is near the minimum discharge
value.
In case the supply is restored before the battery is completely
discharged, the system will be switched back to normal operation
automatically. In the opposite case, the inverter shuts down and the
loads supply is interrupted as soon as the battery reaches the discharge
limit threshold (black-out).
As soon as the supply is restored, the UPS will recharge the battery
.
