When the input voltage is within acceptable range, the UPS
will supply pure and stable AC power to connected loads.
The UPS will also charge the battery in online mode.
Energy saving mode:
When the input voltage is within the voltage regulation range,
the UPS will bypass voltage to loads for energy saving.
When input frequency is between 40 Hz and 70 Hz,
the UPS can be set at a constant output frequency,
50 Hz or 60 Hz. The UPS will still charge the battery when
operating in this mode.
When the input voltage exceeds the acceptable range or
during a power failure, the UPS will start supplying power
from the battery while the alarm will beep every 4 seconds.
When input is within acceptable voltage range but the UPS
is overloaded, the UPS will transfer to bypass mode or it can
be manually changed to bypass mode using the front panel
controls. The alarm will sound once every 10 seconds
in this case.
The UPS is powered off and there is no power supplied to
the loads, but batteries can still be charged.
