<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features:<br/>1.Three-stage intelligent charging design, high efficiency and safety, prolonging the battery service life<br/>2.Constant current charging technology, ensuring stable current output and avoiding the risk of overcharging.<br/>3.Support AC 12-20V and DC 15-30V input voltage range, suitable for a variety of power supply environment.<br/>4. High-precision voltage control reduces charging loss and improves charging efficiency.<br/>5. Compact and portable design, simple installation, wide range of applications</p><p>Product Description: The module adopts CN3768 charge management IC lead-acid batteries must use three-stage charging, the charging process for the automatic charging process, constant current, constant voltage and float charging are three stages of three-stage charging must be. Three-stage lead-acid battery charger charging process is as follows:<br/>1. Constant current charging stage, the charger charging current is kept constant, the charging power increases rapidly and the battery voltage rises;<br/>2. Constant voltage charging stage, the charger charging voltage remains constant, the charging capacity continues to increase, the battery voltage rises slowly, and the charging current decreases;<br/>3. The battery is full, the charging current drops below the float conversion current, the charging voltage of the charger decreases to the float voltage; 4. Float charging stage, the charger charging voltage is maintained at the float voltage.</p><p>Parameter:<br/>AC input interface: low voltage AC input interface, AC12-20V<br/>DC input interface: DC input interface, DC15-30V<br/>Battery interface: connect 12V lead-acid battery, B+ battery positive pole, B-battery negative pole<br/>Indicator light: LED1 charging status light, lighted during charging process<br/>LED2 battery access indicator, access to the battery indicator lights up</p><p>Package include:<br/>Charging module *1<br/><br/></p></div></div><br/>
