Product Features: ★ the Module Uses the Domestic High-Quality Lm2596Chip, High Efficiency (92%), at the Same Time, the Heat Is Small, and It Can Be Very Light and Loose3A Or MoreCurrent, at the Same Time, Cooperate with the Original Ti Operational Amplifier to Control the Output Current, Making the Overall Output Very Stable. ★ This Module Uses Low ESRThe Original Sanyo Filter Capacitor Can Reduce the Ripple Voltage to 50mV！ ★ This Module Uses Machine Patches and Reflow Welding. at the Same Time, Each Module Has Undergone Two Hours of Aging Test before Shipment to Ensure High Reliability. ★ The Shop Owner Likes Electronic Production since Childhood, and He Has Participated in Two National College Student Electronic Design Competitions (Sophomore and Senior) in College and Achieved Good Results, after Graduation, I Have Been Engaged in the Design and Research and Development of Electronic Circuits. I Have Rich Experience in Electronic Design and Programming. We Look Forward to Sharing Our Design Results and Application Experience with You. ★The Power Module Is Available in the Whole Market, and the Order Will Be Delivered Within 24 Hours,

This Module Is Adjustable Step-down Module, and the Output Voltage Can Be Changed by Adjusting the Blue Adjustable Resistor on the Module. The Input and Output Differential Pressure Is 2V, and the Minimum Output Voltage Is 1.23V.

★the in-(Input Negative), in (Input Positive), out-(Output Negative), and out (Output Positive) Indicated on the Module Must Be Correctly Connected. Otherwise, the Module May Be Damaged.

★Battery Charging Usage:
1. Determine the Float-Charge Voltage and Charging Current of the Rechargeable Battery and the Input Voltage of the Module;
2. Adjust the Constant Voltage Potentiometer and Adjust the Output Voltage to about 5V.
3. Measure the Output Short-Circuit Current with Multimeter 10a Current Block, and Adjust the Constant Current Potentiometer at the Same Time to Make the Output Current Reach the Predetermined Charging Current Value;
4. Charging Turn Light Current the Default Shipment Is 0.1 Times the Charging Current (Constant Current Value). If You Need to Adjust It, Adjust the Turn Light Current Potentiometer; (Generally, You Do Not Need to Adjust It)
5. Adjust the Constant Voltage Potentiometer to Make the Output Voltage Reach Float-Charge Voltage;
6. Connect the Battery and Try to Charge It.
(Step 1, Step 2, Step 3, Step 4 and Step 5 Are the Module Input and Power Supply, and the Output Is No Load and No Battery Is Connected.)

★LED Constant Current Drive Usage:
1. Determine the Work Current and Maximum Operating Voltage of the LED You Need to Drive;
2. Adjust the Constant Voltage Potentiometer and Adjust the Output Voltage to about 5V.
3. Measure the Output Short-Circuit Current with Multimeter 10a Current Block, and Adjust the Constant Current Potentiometer at the Same Time to Make the Output Current Reach the Predetermined Led Work Current;
4. Adjust the Constant Voltage Potentiometer to Make the Output Voltage Reach the LED Working Voltage;
5. Connect the LED and Test the Machine.
(1, 2, 3, and 4 Steps Are the Module Input Power Supply, and the Output No-Load LED Light Is Not Connected.)
