Lead Acid Battery Charger Module

12 volt, 3 Ampere 1-1000AH Lead Acid Battery Charger Module

Want to charge 12 volts Lead Acid Battery? Then this DD30CRTA module is perfect for your application. This Lead Acid Battery charger module is specially designed for charging 12 Volt lead acid battery in trickle charge, constant current charge, over-charge and float charge mode.

The DD30CRTA is a PWM switch-mode battery charger controller for 12 Volts lead-acid battery in a small package using few external components. This Lead Acid Battery Charger Module is specially designed for charging 12 Volts lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode. In over-charge and float charge mode, the regulation voltage is internally set.The constant charge current is programmable with a single sense resistor.

Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed constant charge current until the cell voltage exceeds 75% of the regulation voltage in over-charge mode. The over-charge is terminated once the charging current drops to 38% of the constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in float-charge mode. DD30CRTA will automatically enter sleep mode when input voltage is lower than battery voltage. Other features include under voltage lockout and status indication.

Over charge voltage

When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant charge current, the charger goes into float-charge mode.

Float Charge Mode

After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the battery voltage is regulated to 91.57% × VOC, namely 13.55 Volt (Typical). Float charge mode can compensate for the loss of battery power due to self-discharge or external loading.
