The output current can be as high as 3A, and the normal stable working current is 2A The voltmeter can be turned off, press and hold the switch for more than 1 second and less than 4 seconds, and release it to turn off
- Application range: LM2596 DC-DC adjustable step-down module can be used in the step-down field where the input voltage is higher than the output voltage, such as power transformers, DIY adjustable regulated power supplies, 24V car notebook power supplies, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
- Buck Converter Notes: The maximum output current can be as high as 3A, the recommended working current is about 2A, if it exceeds 2A, add a heat sink When encountering the problem that the output voltage cannot be adjusted and is always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally. Because this step-down module leaves the factory, the default output voltage is about 20V.
