Automatic battery charger 14-15V input with 3A max current

automatic battery charger circuitAutomatic battery charger circuit is possible to realize a battery charger with excellent quality that allows it to recharge the 12 volt car battery and dry battery used in the
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.automatic battery charger pcb
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.Automatic battery charger assembly

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
