Its adjustable output voltage range is 0-32.00V, step by 0.01V.Its adjustable outputcurrent range is 0-3.000A, step by 0.001A. This module has power-down stored function and can store 10 groups preset value. And it also has the function of extracting quickly two groups stored value. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltageor currentrequired.LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc. on the output state remind area, you can see that output opens or not, the state of constant voltage and constant current, output is normal or not, the key is locked or not, and the current data groups that is being used. On the setting data interface, you can adjust overvoltage value, overcurrent value, over-power value, data set and LCD brightness. This module has many advantages, small size, advanced function, good visual effect, high operability, high-precision, being used independently, being inset into the device and been widely applied.Technical parameters:Input voltage range:6.00-40.00V Output voltage range:0V-32.00VOutput current:0-3.000AOutput power range: 0-96WProduct Weight: about 90g Product Dimension: 79*43*41(mm) (L*W*H)Open size:71mm*39mmOutput voltage resolution: 0.01VOutput current resolution: 0.001AOutput Voltage accuracy: (0.5% + 1 digits)Output Current accuracy: (0.5% + 2 digit)NOTE: You must make sure that the input voltage is 1.1 times higher than output voltage. Under large current circumstances, pay attention to heat elimination. Connection description:IN+: Input positive IN-: Input negative:OUT+: Output positive: OUT-: Output negativeNote: Input voltage range is DC 6-40V and 40v is the limit voltage; please leave a room to use. Or else it will be burnt. The input must be DC power supply, not AC 220V, or else it will be burnt too. Though this module has reverse connection protection and output short circuit protection, you can muse be in strict accordance with connection description to connect. If you connect the supply power with output, the module will be burnt.Panel description:1-Voltage setting/Page up to choose/Shortcut extract M1 data group2-Data setting/ Extract value of the specified data group/Store value into the specified data group3-Current setting/Page Down to choose/Shortcut extract M2 data group4-1.44 inch color LCD screen5-Coding potentiometer/Data adjustment/Lock all buttons6-Open or close outputDisplay interface description7-The preset value of output voltage8- The actual value of output voltage9-The actual value of output current10-The actual value of output power11-The actual value of input voltage12-The preset value of output current13-Key lock or unlock prompt14-Output normal or not prompt15-Constant voltage and constant current status prompt16-Data set prompt17-Open or close output prompt18-Preset output voltage19-Preset output current20-Preset over- voltage21-Preset over-current22-Preset over-power23-Preset screen brightness24-Preset data set25-The actual value of output voltage and output currentOperating instructions:When connect the power supply, the screen shows welcome window firstly and then comes into main interface. On the main interface, the output set voltage value and the output set current value is on the top of the screen. The big font value on the left are the current real output voltage, the current real output current and the current real output power. Input voltage is on the bottom of the screen. There are some running status icons on the right of the screen, key lock icon, abnormal output status icon, constant voltage and constant current icon, data set tip icon and opening or closing output icon.Set the output voltage and output current on the main interface.Press V/key shortly, you can enter into voltage setting status. Then press the codingpotentiometer, and then enter to adjust the numerical value. Press coding potentiometer to enter into the status of adjusting the numerical value you want to adjust. Turncoding potentiometer to adjustthe numerical value. Turn by clockwise rotation to increase the numerical value; Turn by counterclockwise to decrease the numerical value. If you want to exit adjusting the numerical value,press shortly V/.In the same time the preset value will be stored. Or you can do nothing in one minute, the status will be aut
