alarm system. Operation is completely automatic, because it connects battery, battery charger will only charge the battery if it runs out, because it automatically disconnect the batteries fully charged. This device is supported by transformer with secondary voltage is 14-15 volts with a minimum of 3 Ampere current.
The adjustment of the trimmer TR1 is a way you do, the output of the battery charger, a voltage of about 14.4 volts with no load. The maximum current of 3 Amperes for distribution, it is therefore advised to NOT try to recharge batteries with a Superior capacity 36Ah.
The use of this Automatic battery charger device is perfect for charging batteries for alarm systems with battery buffering. During the insertion, so be careful with the connection to the battery with the AC polarity. For mounting components, you must carefully follow the completion of the scheme.
