2.2 How the Product Works
During normal operation
This UPS operates with AC power as input and supplies constant voltage
output to connected devices. At the same time, it charges the product's
built-in battery to prepare for battery operation. The output frequency is
synchronized with the input frequency.
Electricity flow during normal operation
Battery power failure
If a power failure or input power voltage/frequency error occurs, the UPS
starts discharging from the battery and continues to supply stable power to
the connected device. The system switches to battery operation without
interruption. When the input power is restored (when the voltage of the
input power returns to within the rating), the UPS automatically returns to
the normal operation described above.
