DC-DC Display 3A Adjustable Voltage Regulator Without Box
This circuit is an adjustable DC-DC regulator with an LCD screen that can display voltage and current at the same time. This module has two buttons and adjusts the voltage. This product does not have a protective box. It has a protective box. modele
here You can reach it.
This product is a voltage reducer. It cannot provide an output voltage higher than the input voltage.
Calibration method:
In the power off state, press and hold the left key and turn on the source, when the screen starts flashing, press the left key, measuring the multimeter output voltage, pressing the left and right key to make the multimeter measuring voltage such as 5.V Adjust to 5V, 4.98V or 5.02V is also ok, in this case, please ignore the display of this item. After adjustment, please turn off and on again, then the errors can be calibrated at 0.04V, if the error is larger. You can try calibrating it.
