Super Debug LM2596 DC-DC Adjustable Buck Converter Module 4.0~40V to 1.25~37V Power Supply Transformer with LED Display Electronic Components Electronic Hobby Kit

Parameters: Output Voltage: DC 1.25~37V(continuously adjustable) Input Voltage: DC 4~40V(the input voltage should be higher than output voltage at least 1V) Output Current: 2A(for stable operation), 3A max. Voltmeter Accuracy: .+/-0.1V It adopts 150KHz internal oscillation frequency and belongs to the second generation switching voltage regulator. It has low power consumption and high efficiency. Note: Short press the button can switch the voltage display between input and output, red LED lights on when testing input voltage and green LED lights on when testing output voltage. With voltmeter display, voltmeter error ± 0.1V, range 0 ~ 45V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V) Touch the button to switch the measurement input or output voltage, and there is an indicator to indicate which voltage is being measured, and keep the last setting, even if it is powered off and then on. With terminal block, it can be easily used without soldering, and the wire bond point is retained.
