ITEM NAME:LM2596S Digital Display Power Supply DC-DC Adjustable Buck Module (Blue) A#S Product Description Description: Features: 1. With voltmeter display, using advanced microprocessor, the voltmeter error is  ±0.05V, the range is 0-40V (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V). 2. Tap the right button to switch the measurement input or output voltage, and an indicator light indicates which voltage is being measured, and save the settings, even if the power is turned off and on. 3. Tap the left button when you don't need it to easily turn off the voltmeter. 4. With terminal block, no soldering iron can be used conveniently, and retain the wire bond point 5. The input voltage is 4.0-40V (the input voltage must be 1.5v higher than the output voltage). 6. The adjustable output voltage range is 1.25V~37V, which is continuously adjustable (the input voltage must be 1.5V higher than the output voltage). 7. The maximum output current can be as high as 3A, and the normal stable operating current is 2A. 8. With 150KHz internal oscillation frequency, it belongs to the second generation of switching voltage regulator, with low power consumption and high efficiency. 9. With overheat protection and short circuit protection. Specification: Color: blue board Packing size: 110x70x13mm/4.3x2.8x0.5in Package weight: 20g Note: Please allow slight size differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understand.
