Product Description

This module can be applied to fields in the inputvoltage is higher than the step-down output voltage,such as batteries, power transformers, DIY adjustablepower supply, 24V Car T of the power equipmentindustry buck,12V switch 3.3V, 12V switch 5V,24Vswitch 5V, 24V switch 12V, 36V 24V turn and so on.

Parameters:

1.Product name: LM2596ADJ DC- DC Step-down powerModule(Step Down Adjustable With Digital DisplayScreen); 2.Product size:66mm*36mm*14mm (lxw xh); 3.Colours:Blue; 4.Package Weight:23g/pcs.

Size：

·With a voltage meter and voltmeter displays self-calibration. Uses a more advanced microprocessor voltage voltmeter error±0.05V, Range 0～40V. (To ensure accuracy voltmeter, make sure the input voltage of 4.5V and above); ·Touch of a button to switch the input or output voltagemeasurements and has a light show which is beingmeasured voltages, and save the settings, even thepower off and then on; ·Input Voltage 4.5~ 40V.(Input voltage must be higherthan the output voltage of 1.5v or more); ·Adjustable output voltage range of 1.25V～37V continuously adjustable.(Input voltage must be higherthan the output voltage of 1.5V); ·Output current 3A, recommendations within 2.0A use,high current needed to enhance heat dissipation; ·Output power 20W, 15W, please enhance heatdissipation over; ·High conversion efficiency, on average 88%(efficiencyand the input and output voltage, current, pressurerelated); With reverse polarity protection, reverse polarity doesnot burn.

Product Usage

·Onboard voltage table shows the output voltage,long press on the right button for 2 seconds after the release, voltmeter and the output voltage indicator "OUT" synchronous flashing, this time into an output voltage adjustment mode; Similarly, the voltmeter shows when the input voltage, long press the Right button 2 seconds after the release, voltmeter and an input voltage indicator "IN" synchronous flashing,then enter the adjustment mode input voltage; ·Touch the right side of the button, the voltageincreases one unit, touch the left button, voltagereduction unit; because the voltage is less than thevalue of a unit of 0.1V, so you need to press the 1-5times in a row to see the voltmeter change of 0.1V,concrete continuous button several times dependingon the voltage value currently displayed, the currentdisplay higher the voltage, the fewer the number ofpresses; ·When the voltage is adjusted, long press on the rightbutton for 2 seconds after the release, then you canexit the voltage calibration mode, all parameters setto automatically power down to save. ·Note: this way you only need to adjust the calibrationonce to get precise voltage values over the entirevoltage range, this feature is designed to meet yourrequirements and design a higher accuracy, ease of use.

·Note:

1.When the module output voltage can not be adjusted, the output voltage is always equal to theinput voltage.Please adjust the potentiometer counterclockwise 20 laps or more.(Let potentiometeragainst your chest, counterclockwise turn boost); 2. Input voltage must be higher than the outputvoltage of 1.5v or more; 3.high current or high power needed to enhance heat dissipation.
