LM2596S high-power step-down 4-40V to 1.25-37V 4A module DC-DC adjustable voltage regulator power supply module with digital display

LM2596S high-power step-down module DC-DC adjustable regulated power supply module with digital display

With power indicator

● With voltmeter display, advanced microprocessor, voltmeter error ±0.05V , range 0~40V . (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V )

● Tap the right button to switch between measuring input or output voltage, and there is an indicator light showing which voltage is being measured, and the setting is saved , even if the power is turned off and on again 

● Voltmeter can be turned off , when it is not needed, it can be easily realized by tapping the button on the left side 

● With terminal blocks, it is easy to use without soldering iron, and the connection points of welding wires are reserved 

Input voltage 4.0~40V (The input voltage must be higher than the output voltage by more than 1.5V . ) 

● Adjustable output voltage range 1.25V ~ 37V continuously adjustable ( input voltage must be 1.5V higher than output voltage ) 

● The maximum output current can be as high as 3A , and the normal stable working current is 2A 

● Using an internal oscillation frequency of 150KHz , it belongs to the second generation of Di switching voltage regulator, with low power consumption and high efficiency. 

● With overheating protection and short circuit protection function 

 Size: 56MM*30MM
