Stable mains
Whenever stable mains is present, the device charges the battery and displays the current
charge on the panel.
If the device is turned on and the mains is off or unstable, it automatically switches to
battery powered mode.
If the mains is not available, the indicator goes off, if the mains voltage is not within the
specified limits the indicator blinks.
Battery power
Switching to battery powered mode a continuous sound is made in the time of transition
and then a short one every 30 sec.
The time to operate on battery power depends on the capacity, charge and condition of
the connected battery, as well as the power of the load connected. When the battery
charge goes below 10%, the device beeps every 2 sec until the battery voltage goes below
10.2 V, then the device automatically shuts down. When the mains is restored, the device
automatically turns on and starts charging the battery.
In case of connecting a load that is more powerful than the device rated output power or
short-circuit of the output, the
LED lights up and the power to the load is cut off. The
UPS will attempt 10 retries in 10 sec to restore the power to the load and if the overload
condition is removed will go back to normal battery power operation.
