DD30CRTA Lead Acid Battery Charger 12V Charging Device 3A Current 1-10000AH UPS Solar Power Module

The DD30CRTA is a compact PWM switch-mode battery charger controller designed specifically for 12V lead-acid batteries, requiring only a few external components for operation. It supports various charging modes including trickle charge, constant current charge, over-charge protection, and float charge. In over-charge and float charge modes, the regulation voltage is pre-set internally for convenience. The constant charge current can be programmed using a single sense resistor.

For deeply discharged batteries, the DD30CRTA automatically initiates a trickle charge at 17.5% of the programmed constant charge current until the cell voltage surpasses 75% of the regulation voltage during over-charge mode. Over-charge is ceased when the charging current drops to 38% of the constant charge current, transitioning the device into float charge mode. If the battery voltage falls below 83.95% of the over-charge voltage during float charge mode, a new charge cycle is automatically initiated. Additionally, the DD30CRTA enters sleep mode when the input voltage drops below the battery voltage, conserving energy and optimizing efficiency.
