As a Battery Charger

Module without constant function can not be used to charge the battery, because the complete consumption of battery charger great preure, leading the charge current is too large, causing damage to the battery, so when the battery begins to use a constant current charging when the charge to a certain extent, when to automatically switch back to the constant voltage charging.

Usage:

1. Make sure you need to charge the battery float voltage and charging current.

2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.

3. Use the multimeter (10A) to measure the short circuit current and adjust the constant current potentiometer to make the output current reach the predetermined charge current value.

4. Recharge the light current by default to 0.1 times the charge current (constant current value).

5. To adjust the output voltage of the constant voltage potentiometer to float voltage.

6. battery, test charge.

(1, 2, 3, 4, 5 steps for module input power supply, output no-load non battery.)

Use as a normal buck modules with over-current protection capabilities

1. Determine that you need to drive the LED's working current.

2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.

3. Use the multimeter(10A)current gauge to measure the short circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED working current.

4. Constant voltage potentiometer makes the output voltage reach LED.high working voltage.

5. LED test machine.

(1, 2, 3, 4 steps for module input power supply,output no-load no LED lamp.)

This module is more than 5A in use, to enhance heat diation.

Package included:

1 x DC Buck Converter

Note:

When use this module,can not combine input GND and output GND.

The IN above the module (input negative), IN+(input positive), OUT-(output negative), OUT+(output positive)must be correct, otherwise the module may cause damage to the module.
