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
(±3%V max), the UPS will bypass voltage to loads for
energy saving. PFC and INVERTER are still active in this
mode.
When the input voltage is within the voltage regulation range
(±3%V max), the UPS will bypass voltage to loads for
energy saving. PFC and INVERTER are disabled in this
mode.
When input frequency is between 40Hz and 70Hz, the UPS
can be set at a constant output frequency, of 50Hz or 60Hz.
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 5 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.
The UPS is in fault mode when it fails to provide output
power to the loads. The fault icon flashes on the LCD
display even though the UPS information is still being
displayed on the screen.
