3pcs XL4015 5A DC-DC Step Down Charger Modules, CC CV Lithium Battery Charging Board, LED Power Converter
- Feature Size: 5.2 x 2.65 x 1.4cm (L x W x H) Module Properties: non-isolated constant current and voltage module Rectification: non-synchronous rectification Input voltage: 5V-32V Output voltage: 0.8V-30V Output current: adjustable maximum 5A Conversion efficiency: 95% (the highest) Switching frequency: 300KHz Output ripple: 50mV (max) 20M bandwidth Load Regulation: ± 0.5% Voltage Regulation: ± 2.5% Operating Temperature: -40 °c to +85 °c This module is an adjustable step-down module, you can change the output voltage by adjusting the blue adjustable resistor on top of the module. The input/output voltage difference is 1V and the minimum output voltage is 0.8V. Make sure to connect IN-(input negative), IN+(input positive), OUT-(output negative), OUT+(output positive) correctly, otherwise the module may be damaged. Battery charging How to use: 1. 1. Determine the floating voltage and charging current of the battery you need to charge, and the input voltage of the module; 2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V. 3. 3. Measure the output short-circuit current with a multimeter 10A current stop, and adjust the constant current potentiometer to make the output current reach the predefined charging current value. 4. Charge the lamp current default shipping for 0.1 times the charging current (constant current value). 5. Adjust the constant voltage potentiometer so that the output voltage reaches the float voltage. 6. Connect the battery
