Automatic and Intelligent 9-Stage Charging Characteristic
The AS1210 is controlled by a 12-bit AD microprocessor with 9-stage charging
characteristic for charging batteries automobiles, motorcycles, snow mobiles, tractors,
personal watercraft, boats etc.
A microprocessor senses the condition of the battery and controls the regulator to
provide the right current and voltage to the battery (charging characteristic). This will
give the best effect on charging and give the longest life to battery.
Charging characteristic:
• Diagnosis & Recovery: Initial battery test to determine battery condition. If in
normal condition (battery voltage >10.5V±0.25V) the pulse charging will be skipped
and charging starts with Bulk charging. If the battery is severely discharged ("dead",
battery voltage <10.5V±0.25V), the charger changes to pulse charging mode in order
to rescue most of dead batteries. In this mode the battery will be charged with 1,5A
and 3.5A charging impulses until reaching the normal condition of 10.5V±0.25V and
then continues with bulk charging
• Bulk: Major charging stage where the battery receives the majority of its charge.
During this stage the battery brought to 80% of its capacity. The AS1210 charger
delivers current from 7.0A to 3.0A.
• Absorption: Completes the charge up to virtually 100% at a constant current of
1.5A
• Trickle Charge: Trickle charging at constant voltage, keeping the batteries at 100%
charge. When 100% charged the AS1210 goes into maintenance mode to test the
battery and if necessary repeats the charging.
Temperature Compensation
A sensor will automatically adjust the charging current if the temperature deviates from
0°C to +40°C. If the charger is too hot for some reason, it will reduce the output power
automatically to protect itself from damaging.
