XL4015E High current Stepdown โมดูลสเตปดาวน์แปลงไฟ 5-32V to 0.8-30V 5A กระแสสูงสุด 5A

5A constant voltage constant current module

When you use this product the input and output grounds of the module should not be shared together. This will cause the boards high-power current sampling resistor to be bypassed thus making it impossible for the module to adjust the output current and it will be easily burned under load. The power chip on the module.

This module is easy to use and powerful! ! ! A module has 3 major functions to meet your most occasions! ! !

Module highlights:

1. High power high efficiency 5A low ripple
2. Three in one:
Use as an ordinary buck module with overcurrent protection capability
As a variety of voltage value lithium battery battery nickel-cadmium nickel-metal hydride battery (battery pack) charger for solar panels wind turbines and other occasions
Use as a high-power LED constant current driver module
3. With constant voltage and constant current two modes there are indicators to indicate which mode the module is currently in

4. When used as a lithium battery charger you can set the float voltage and charge current with indicator light
Is it charging or already full?

5. With current limit protection even if the output is short circuit it will not burn out the module.

The scope of application
Use as an ordinary buck module with overcurrent protection

Instructions
Adjust the constant voltage leveler so that the output voltage reaches your desired voltage level
Measure the output short-circuit current with the 10A current meter of the multimeter (directly connect the two test leads to the output terminal) and adjust the constant current potentiometer to make the output current reach the predetermined over-current protection value. (For example the current value displayed by the multimeter is 4A then when you use the module the maximum current can only reach 4A. When the current reaches 4A the red constant voltage constant current indicator is on otherwise the indicator is off)
Note: When used in this state since the output has a current sampling resistance of 0.05Ω there will be a voltage drop of 0~0.3V after the load is connected. This is a normal phenomenon! This voltage drop is not pulled down by your load but drops to the sampling resistor.

Use as a battery charger

The module without constant current function can not be used to charge the battery. Because the voltage difference between the battery and the charger that consumes electricity is very large the charging current is too large and the battery is damaged. Therefore the battery must be used at the beginning. Stream charging automatically switches back to constant voltage charging when charging to a certain degree.

Instructions
Make sure that you need the float voltage and charge current of the rechargeable battery; (if the lithium battery parameter is 3.7V/2200mAh then the float voltage is 4.2V the maximum charge current is 1C ie 2200mA).
Under no-load conditions Multimeter to measure the output voltage adjust the constant voltage leveler so that the output voltage reaches the float voltage; (If you charge the 3.7V lithium battery adjust the output voltage to 4.2V)
Measure the output short circuit current with the 10A current of the multimeter. (Directly connect the two test leads to the output terminal) and at the same time adjust the constant current potentiometer to make the output current reach the preset charging current value;
The charge turn lamp current default factory is 0.1 times charge current; (The battery is charging The current is gradually reduced and it is gradually converted from constant current charging to constant voltage charging. If the charging current is set to 1A when the charging current is less than 0.1A the blue lamp is off and the green lamp lights up. At this time the battery is turned on. Charging is completed.
Connect the battery and charge it.
(Steps 1 2 3 and 4: Input is connected to the power supply output is not connected to the battery)


3. Use as high-power LED constant current drive module

Make sure that you need to drive the LEDs operating current and maximum operating voltage;
Under no-load conditions the multimeter measures the output voltage and adjusts the constant voltage l
