AUTOMATIC ENTRY BATTERY CHARGER 14-15 VOLT AC COURANTMAX 3 AMPERES
SCHEMA AUTOMATIC BATTERY CHARGER 14-15 VOLT AC CURRENT MAX 3A:
The assembly can achieve an excellent quality battery charger with which it is possible to recharge batteries from 1 to 2 volts car, and dry batteries of the systems used in alarm. Operation is completely automatic since, connect a battery, it will take office only if it is discharged, while it will automatically disconnect from the battery to be charged. The device is powered by a transformer whose secondary is 14-15 volts with a current of 3 Amperes minimum.
The adjustment trimmer TR1 is to have effectuede way, the output of the battery charger, a voltage of about 14.4 volts with no load. Distributable maximum current of 3 Amperes, it is therefore advised NOT to try recharging batteries with a capacity superieurede36Ah. Perfect use of this device is that of supplying a battery charger for alarm system with buffer battery.
During insertion, we must be very careful with connections to the battery respecting polarity AC.
For mounting of components , you must carefully follow the settlement scheme.
