XL4015 5A CC CV Lithium Charger DC-DC Step Down Module Board
Product Details:
Input Voltage 8V to 36V Storage Temperature -65 to 150 Deg C Operating Temperature -40 to 125 Deg C Minimum Drop Out 0.3 V Output Adjustable Voltage 1.25V to 32V Maximum Duty Cycle 100 This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 0-5A (Max) Adjustable load with high efficiency,
low ripple and excellent line and load regulation. Use as a step-down modules with overcurrent protection capabilities
The DC/DC buck module has applications where the input voltage is higher than the output voltage , such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TVportable instrument power supply telecom/networking equipment,24V vehicle notebook power supply,industrial equipment buck. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V etc.Applications:
- Use as a step-down modules with overcurrent protection capabilities
Usage:- Adjust the voltage potentiometerso that the output voltage reaches the value you want.
- Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the current potentiometer so that the output current reaches a predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
- Connect the load.
Use as a battery charger
Usage:
- Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
- Under no-load conditions, adjust the Voltage potentiometer so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
- Use a multimeter to measure the output short-circuit current, while regulating the current potentiometer so that the output current reaches a predetermined Charging current value.
- Factory default is 0.1 times the charging current; (during charging,current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)
- Connected to the battery charge. (1,2,3,4 steps as: Output is unloaded, do not connect the battery)
3.Use as a LED constant current driver module
Usage:
- Adjust the voltage potentiometer so that the output voltage reaches the value you want.
- Use a multimeter to measure the output short-circuit current, while regulating the current potentiometer so that the output current reaches a predetermined LED operating current.
- Connect LED, work. (1,2 steps as: Output is unloaded, do not connect LED)
