DC-DC Step Down Power Supply Adjustable Push-button Module with LCD Display
1, Beautifully acrylic Enclosure.
2, Using STN liquid crystal display screen, Voltage and Current can be displayed simultaneously, blue background and white character, wide angle and wide field of view.
3, Using button adjustable voltage, left button to reduce the voltage, the right button to increasing voltage. press button one time can adjust 0.04V voltage, press and hold more than 1 second to quickly adjust voltage.
Calibration Mothod:
Power-off status, press and hold the left button access the power, the display starts flashing, release the left button. using multimeter measured the output terminal voltage, if the measured voltage is greater than 5V, press the left button reduced the voltage to 5V; if the voltage is less than 5V, press the right button to increase the voltage to 5V. When the LCD display voltage of 5V(sometimes it shows 4.99V), turn off the power, the calibration is complete.
