Lm2596 Modules on the Market Do Not Have Output Short Circuit Protection. If the Output Is Short-Circuited, the Module Will Be Damaged Immediately and the Current Output Capacity Will Be Less than 1.8A. This Module Adopts Original Lm2596, Large Chip, Frosted Surface, Output Short Circuit Protection, High Current 3A.

Module Highlights:

1. Comfortable Price, Intelligent and Humanized Design, with Cost Performance!

2. on-Board Voltmeter, Voltmeter Can Be Self-Calibrated, There Will Be No Problem of Voltmeter!

Module Performance and Features:

● with Voltmeter Display and Voltmeter Self-Calibration. More Advanced Voltage Microprocessor Is Adopted, Voltmeter Error ± 0.05V, Range 0~40V. (to Ensure the Accuracy of Voltmeter, Please Ensure That the Input Voltage Is above 4.5V)

● Touch Button to Switch the Measuring Input Or Output Voltage, and There Is an Indicator Light Showing Which Voltage Is Being Measured, and Save the Setting, Even If the Power Is off and Then Turn on.

● The Voltmeter Can Be Closed, and It Can Be Easily Achieved by Touching Button on the Left When It Is Not Needed.

● with Wiring Terminal, It Is Convenient to Use without Soldering Iron, and Bonding Wire Wiring Points Are Retained.

● Input Voltage 4.0~40V. (the Input Voltage Must Be More than 1.5V Higher than the Output Voltage)

● Adjustable Output Voltage Range: 1.25V ~ 37V Continuously Adjustable. (the Input Voltage Must Be 1.5V Higher than the Output Voltage)

● The Output Current Is 3A. It Is Recommended to Use It Within 2.0a. Large Current Needs to Enhance Heat Dissipation.

● Output Power 20W, More than 15W Please Strengthen Heat Dissipation.

● High Conversion Efficiency, with an Average of 88% (Efficiency Is Related to Input, Output Voltage, Current and Differential Pressure)

● with Reverse Connection Protection, Reverse Connection Does Not Burn

● It Has the Functions of Overheating Protection and Short Circuit Protection.

● Size 6.1*3.4 * 12cm (Length * Width * Height)

● Weight: 22G

Application Scope:

This Module Can Be Applied in the Step-down Field Where the Input Voltage Is Higher than the Output Voltage, Such as Battery, Power Transformer, DIY Adjustable Regulated Power Supply, 24V Vehicle-Mounted Pen Book Power Supply, Industrial Equipment Step-down, 12V to 3.3V,12V to 5V,24V to 5V,24V to 12V,36V to 24V, Etc.

Self-Calibration Method of on-Board Voltmeter:

1. When the on-Board Voltmeter Displays the Output Voltage, Press Button on the Right Side for 2 Seconds and Then Release It. The Voltmeter and the Output Voltage Indicator Light "out" Flash Synchronously, and Then Enter the Output Voltage Adjustment Mode; Similarly, when the Voltmeter Displays the Input Voltage, Press Button on the Right Side for 2 Seconds and Then Release It. The Voltmeter and the Input Voltage Indicator Light "in" Flash Synchronously, and Then Enter the Input Voltage Adjustment Mode;

2. Touch the Right Side Button, the Voltage Rises by One Unit, Touch the Left Side Button, the Voltage Decreases by One Unit; Because the Voltage Value of One Unit Is Less than 0.1V, therefore, You Need to Press 1-5 Times Continuously to See That the Voltmeter Has Changed by 0.1V. the Specific Number of Consecutive Button Times Depends on the Current Displayed Voltage Value. The Higher the Current Displayed Voltage, the Less the Pressing Times;

3. after the Voltage Adjustment Is Completed, Press Button on the Right Side for 2 Seconds and Then Release It. at This Time, the Voltage Calibration Mode Can Be Exited. All Parameter Settings Are Automatically Powered down and Saved.

Note: This Adjustment Method Only Needs to Be Calibrated Once to Obtain the Voltage Value over the Entire Voltage Range. This Function Is Designed to Meet Your Higher Precision Requirements. Please Feel Free to Use It.
