OVERVIEW

Fit with up-to-date power supply device, battery charger BAC1210 is specially designed for meet the charging characteristics of the lead-acid engine starter batteries and can be used for long-term float charging. It suits 12V battery pack.

PERFORMANCE AND CHARACTERISTICS

It has following characteristics:

1. Switch power supply structure, wide input alternating voltage range, small size, light weight, high efficiency rate;
2. Automatic two-stage charging process (first constant current, then constant voltage) carried out according to storage battery charging characteristics to prevent overcharging and significantly prolong battery lifetime;
3. Built-in current protective circuit, which can give effective protection when output over current, short-circuit or reverse connection occurs. Regard power lamp or charge lamp fast blinking as alarm.
4. Suitable for 12V storage battery and the rated current is 10A;
5. External LED display: Power indication (Green light) and charging indication (Red light).

CHARGING PRINCIPLE

Charging is performed according to the battery charging characteristics by using two-stage method. Charging type of first stage is ‘constant current type’ which means that when the battery terminal voltage falls below the pre- set value, charging current will be constant; Charging type of second stage is ‘floating type’ which means when the battery terminal voltage exceeds the pre- set value, charging current will decrease with the rising of terminal voltage; At this time charging turns to floating charging. As soon as charging current value falls below 0.5A and battery terminal voltage reaches up to the pre-set constant voltage value, the battery is basically full-charged (charging indicator will extinguish). After that charging current will only neutralize the battery self discharge. Even long-term charging cannot harm the battery, as charger can keep the battery fully charged and also guarantee long lifetime of the battery.

EFFICIENCY CURVE

OPERATION

1. Connect terminals L and N to alternating voltage (100-277)V using BVR 1mm2 multi-strand copper line.
2. Connect B+ and B- to battery positive and negative using BVR 2.0mm2 multi-strand copper line.
3. PE terminal inside has already been connected to shell, which is earth terminal.
4. FULL: full charging indicator, it is illuminated when battery is fully charged.
5. CHARGING：charging indicator, illuminated when charging current exceeds 0.5A ,extinguished when charging is completed.

NOTES:

1. Because there is diode and current-limiting circuit inner the charger, it can be used together with charging generator in parallel, and there is no need to disconnect the charger when cranking.
2. During genset is running, high current will cause voltage drop in charging line, so recommend separately connecting to battery terminal to avoid disturbance on sampling precision.
