ماژول مبدل DC-DC کاهنده XL4015 با کنترل شارژ باتری
مبدل DC به DC معماری BUCK کاهنده ولتاژ تا 1.25 ولت و حداکثر جریان خروجی 5 آمپر با کنترل جریان
Introduction
Use as a step-down modules with overcurrent protection capabilities
adjust the “voltage potentiometer” so 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)
Connected to the load.
Use as a battery charger
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 with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined Charging current value.
Charge turn lamp current factory default is 0.1 times the charging current; (Battery 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)
Use as a LED constant current driver module
adjust the “voltage potentiometer” so 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 LED operating current.
Connect LED, work.
(1,2 steps as: Output is unloaded, do not connect LED)
When you use the product, the module inputs and outputs to be isolated from ground
