OVERVIEW

Fit with up-to-date power supply device, float charger BAC2405CF is specially designed for meet the charging characteristics of the lead-acid engine starter batteries and can be used for long-term float charging of 24V lead-acid batteries. The maximum output current is 5A.

PERFORMANCE AND CHARACTERISTICS

• Switch power supply structure, wide input alternating voltage range, small size, light weight, high efficiency rate;
• Automatic two-stage charging process carried out according to storage battery charging characteristics to prevent overcharging and significantly prolong battery lifetime;
• Built-in output current protective circuit, which can give effective protection when output over current, short-circuit or reverse connection occurs. After troubleshooting over current, short-circuit or reverse connection, the output will be recovered automatically.
• With port of mains failure alarm, the port will close immediately while occurring AC input outage.
• Suitable for 24V storage battery. The maximum output current of is 5A.
• LED display: float charging indicator and charging indicator.

CHARGING PRINCIPLE

Two Stage Method

Charging is performed according to the battery charging characteristics using two-stage method.

• The first stage is named as ‘constant current’: when the battery terminal voltage falls below the pre-set value;
• The second stage is named as ‘constant voltage’: 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. As soon as charging current value falls below 0.3A and the constant voltage value is reached, the battery is basically 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 so guarantee long lifetime of the battery.
