Status LEDs The LED on the left comes on to indicate that charging is occurring if the module is being used to charge a battery. The LED on the right comes on to indicate that charging is complete as the current being drawn from the module is reduced toward zero. It switches the LEDs between the two states when the current reaches approximately 10% of the current limit setting.
- This compact DC-DC module is an adjustable XL4015 based voltage step-down (buck) converter module. The module is rated for an input of 5V – 32V with an output voltage of 1.27V – 30V at up to 5A.
- The display shows the output voltage on the top display and output current on the bottom display.
- The potentiometer towards the middle of the module is used for adjusting the output voltage and output current which is shown on the LED display.
- There are 2 LEDs that display the charging state.
