LM2596S high- step-down module DC-DC adjustable voltage regulator supply module with digital displayWith indicatorWith voltmeter display, using advanced microprocessor, the voltmeter error is 0.05V, and the range is 0~40V. (Note: To the accuracy of the voltmeter, please that the input voltage is above 4V)Touch the right button to switch the measurement input or output voltage, and there is an indicator light to show which voltage is being measured, and save the settings, even if the is turned off and then turned on againThe voltmeter can be turned off, and it can be easily achieved by pressing the left button when it is not neededColor: blue, blackMaterial: PCB, MetalWith terminals, it is easy to use without a soldering iron, and the connection points are reservedInput voltage 4.0~40V (The input voltage must be more than 1.5v higher than the output voltage.)The adjustable output voltage range is 1.25V~37V continuously adjustable (the input voltage must be 1.5V higher than the output voltage)The maximum output current can be as high as 3A, and the normal stable working current is 2AUsing 150KHz internal oscillation frequency, it belongs to the second generation switching voltage regulator, with low consumption and high efficiency.With overheat protection and short circuit protectionPackage Contents:6 x Step-Down Regulator ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
