    Product Description:

    • High power, high efficiency, 5A, low ripple;

    • Three in one:

              Use as an ordinary buck module with overcurrent protection capability;

              As a variety of voltage value lithium battery, battery, nickel-cadmium nickel-metal hydride battery (battery pack) charger for solar panels, wind turbines                and other occasions;

              Use as a high-power LED constant current driver module;

    • With constant voltage and constant current two modes, there are indicators to indicate which mode the module is currently in;

    • When used as a lithium battery charger, you can set the float voltage and charge current, with indicator light

    • With current limit protection, even if the output is short circuit, it will not burn out the module.
