LM2596 Buck Converter DC Voltage Regulator Adjustable Step-Down Power Module with LED Display Voltmeter DC to DC 4.0~40 to 1.3-37V

Description

DC-DC adjustable power supply upgrade version LM2596 regulator module with a voltmeter display ● with a voltmeter display, the use of advanced microprocessors, voltmeter error ± 0.05V, range 0 ~ 40V. (Note: to ensure the accuracy of the voltmeter, please ensure that the input voltage of 4V or more) ● Touch the button to switch the measurement input or output voltage, and a light to indicate which voltage is being measured and save the settings, even if the power is turned on again ● The voltmeter can be turned off, when you do not need to touch the left button can be easily achieved ● With terminal blocks, no soldering iron can also be used easily, and keep the wire connection points Input voltage 4.0 ~ 40V (input voltage must be higher than the output voltage above 1.5v.) ● Adjustable output voltage range 1.25V ~ 37V continuously adjustable (input voltage must be higher than the output voltage 1.5V) ● Maximum output current up to 3A, normal and stable operating current at 2A ● 150KHz with the internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption, high efficiency. ● With overheating protection and short circuit protection Specification: Input voltage range: 4~40V DC Adjustable output voltage range: 1.25~37V DC Output current: 2A(for stable operation) Max output current: 3A Volt meter range: 0 to 40V Volt meter accuracy: ±0.1V Internal oscillation frequency: 150KHz
