Valefod 3 Pack LM2596 DC to DC Voltage Regulator 4-40V to 1.5-35V Buck Converter with LED Display

hi welcome to Robo jack in this video we are going to do a test review of this LM two five nine six regulator with the input of four 240 volts and the output of regulated 1.25 to thirty seven volts with the display we are going to test this this can handle up to 3 ampere we are going to see if it can handle 3 ampere Adam under different voltage conditions so let's get started as a step-down converter using the LM two five nine six regulators so this has an LED display that shows the voltage input and output depending on selecting this switch so now it shows the light is on here it shows that the input voltage is 12 point 5 volts if I want to see the output just press this and the light will be on so this shows that the output is now 3 point 7 volts so the first thing I've connected my power supply has 2.3 volts and as you can see here it shows 12.5 so death 12 point 3 is the same as my
