K21 5A CC CV Step-down Power Supply Module Lithium Battery Charger

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
