1 Pcs Lead Acid Battery Charger Module 12V 3A 1-1000AH Lead Acid Accumulator Storage Cell Battery Charger Board for Car Solar Motorcycles
The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.It 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.Constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle.
Over-charge mode. The over-charge is terminated once the charging current drops to 38% of the.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.Undervoltage lockout and status indication etc.
Power supply voltage :15-25V;Over Charge Voltage is 14.8V;Float Charge Voltage is 13.55V;Maximum charge current : 3A;Quiescent current: about 1.8mA;High PWM Switching Frequency:300KHz;Operating Ambient Temperature ?40? to ?85?.
