Principle of operation
MVQUICKAL features an internal battery system of about 21Wh.
This power source is automatically connected to the output
terminals (becoming the only power source) whenever the main V-
Lock battery is not installed, removed or empty (voltage below 12V).
Alternatively, when a V-Lock battery with a voltage greater than 12V
is installed, it becomes the main power source connected to the
output connector.
If, during usage, the V-lock battery voltage drops below 12V, or it is
removed, MVQUICKAL automatically provides a continuous power
supply to the device without any power interruption.
As soon as this switchover takes place and MVQUICKAL operates
through its internal power source, the 3 LEDs become alighted
(depending on the state of charge) to alarm the user that the main
power source, coming from the external V-Lock battery is no more
available and the internal UPS is providing continuity power.
When operating as the main power source, the runtime provided by
MVQUICKAL depends by the state of charge of its internal battery
and the actual power consumption.
The LED array displays the state of charge based on the internal
battery voltage and the following criteria:
