![]() However, when used as a general-purpose power supply, the battery charging indicator LED will work as a ‘load-on’ annunciator. Further, there are three LED indicators – the first one near the input connector is the constant-current (cc) indicator, while next two LEDs are intended mainly for battery charging applications (battery charging and battery full indicators). This is the photograph of my XL4015 Step-Down DC Module with CV/CC Control.Īs you can see, apart from the input and output screw terminal connectors, there are two multiturn trimpots to adjust the output voltage and output current. This is the quick specification chart of the module posted by the seller. This time the module has onboard constant voltage (CV) and constant current (CC) control feature which is useful for general purpose power supply and battery charger applications. ![]() I tried it immediately in a new experiment. I purchased it from an online seller in China. I recently received an improved version of the same module. In an earlier blog post I did a teardown analysis of the XL4015 DC-DC Buck Converter module.
