#1	LM2596 buck converter stably output voltage conversion efficiency is up to 96 The output voltage is 125V37V continuously adjustable the input voltage must be 1V higher than the output voltagethe output current is 2A normal and stable the maximum is 3A
#2	The digital can be turn on or off to show input or output voltage With advanced voltage microprocessor self calibration the voltmeter error01V the input voltage is DC 040V Note To ensure the accuracy of the voltmeter please ensure that the input voltage i
#3	NOTE This is a buck module The input and output connectors cannot be reversed The input voltage must be higher than the output voltage A radiator is required for longterm work above 2A15W When using it for the first time it is necessary to turn the potent
#4	Press the button next to voltmeter to test input voltage or output voltage Green LED lights on when testing output voltage red LED lights on when testing input voltagePress the button for 1 to 4 seconds voltmeter would be shut off when releasing your hand
#5	Analog control using a mini screwdriver to increase or decrease output voltage by adjusting the screw clockwise to step up voltage and counterclockwise to step down voltage
