XL4015 5A DC-DC Step Down Adjustable Power Supply xl-4015 Module Buck Converter
XL4015 5A DC-DC Step Down Adjustable Power Supply xl-4015 Module Buck Converter Battery charging method:
1. Make sure you need to recharge the battery’s float voltage and charge current, the module’s input voltage;
2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3. With the multimeter 10A current block measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current reaches a predetermined charge current value;
4. Charging Turn lamp current default shipment is 0.1 times the charge current (constant current value).
5. Adjust the constant voltage potentiometer so that the output voltage reaches the float voltage;
6. Connect the battery, try charging.(1, 2, 3, 4, 5 steps for the module input power supply, the output does not load the battery.)
LED constant current drive use:1. Make sure you need to drive the LED’s operating current and Z high operating voltage;2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.3. With the multimeter 10A current block measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current to a predetermined LED operating current;4. Adjust the constant voltage potentiometer to make the output voltage to LEDZ high operating voltage;5. Connect the LED, test machine.(1, 2, 3, 4 steps for the module input power supply, the output no-load LED lights.)
