4.5.2 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.
Also, the user can switch to bypass manually using the display of the UPS.
4.5.3 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.
