3A 12V 1-1000AH Lead-Acid Battery Charger for UPS Car

Detailed Information About The Product:

The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery.The DD30CRTA is specially designed for charging 12V 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 undervoltage lockout and status indication, etc.
