The innovative circuitry in the
greater efficiency by reducing energy expenditure. output
current is regulated both according to the needs of service
batteries and to the quantity of input energy. while travelling
the device gradually reduces the output current in the event
that the alternator is in overload conditions (eg: at night with
lights on, air conditioner on, engine idling and engine fan on, etc
...). The cooling fan is activated only if necessary and the
rotation speed is electronically controlled according to the
temperature inside the device keeping fan noise to minimum.
