OVERVIEW
Fit with up-to-date power supply device, battery charger BAC1203VL is specially designed for meeting the charging characteristics of lead-acid batteries and can be used for long-term supplement (float) charging of 12V battery pack.
PERFORMANCE AND CHARACTERISTICS
It has the following characteristics:
- Applies switch power supply structure, wide range and low input voltage, small size, light weight, high efficiency rate;
- Applies automatic two-stage charging process (first constant current, then constant voltage) according to storage battery charging characteristics to prevent overcharging and significantly prolong battery lifetime;
- Short-circuit protection function;
- Suitable for 12V storage battery with maximum charging current 3A;
- LED display: Power indication and charging indication;
CHARGING PRINCIPLE
Figure 1 Charging Principle Diagram
Charging is performed according to the battery charging characteristics by
two-stage method. Charging type is ‘constant current type’, which means that
when the battery terminal voltage falls below the pre-set value, charging
current will be constant; when the battery terminal voltage exceeds the pre-
set value, charging current will decrease with the rising of terminal voltage
until the pre-set current value is reached; then chargers automatically return
to float mode. At this time charging current gets smaller and smaller
gradually. The terminal voltage also gets higher and higher to the pre-set
value gradually. when the charging voltage gets over 13.5V, battery is fully
charged in a degree. Afterwards charging current only offsets battery’s self
discharging. long-term charging does no harm to the battery. That is, charger
can keep the fully charged status of the battery and also can ensure the usage
life of the battery.

Red Indicator| Charging Indicator| It illuminates when the charger is
charging.
Green Indicator| Power Indicator| It illuminates when the charger is working.
NOTE1: When this is applied on genset, charging current shall produce voltage drop on charging line. so it is recommended to separately connect charging line to battery terminals to prevent affecting sensor precision of collecting samples.
