ITEM NAME:DC-DC Adjustable Step Down Power Supply Push-button Module with LCD Display Descriptio n Description: Feature: Using STN liquid crystal display screen, Voltage and Current can be displayed simultaneously. 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. Fine workmanship and good performance. Easy to use. Long service life. Calibration Method: 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. Specifications: Brand new Size: approx. 62*44*18mm Input Voltage: 5~23V, Max 23V, recommended to use within 20V (Input voltage must be higher than the output voltage 1V above, please check the input positive and negative polarity before connecting, reversing polarity may damage the components) Output Voltage: 0~16.5V adjustable ( can save the last set voltage automatically) Peak Current: 3A, recommended use in 2A, accuracy of 1%, the minimum display 0.01A Less than 10mA will not be displayed Conversion Efficiency: 95% Load Regulation S(I): ≠¤0.8% Voltage Regulation S(U) ≠¤0.8% Package Included: 1 * Step-down Power Supply Module 1 * Acrylic Enclosure Kit (need to assembled by yourself) Note: 1.Due to the manual measurement and different measurement methods, the actual size could be slightly different. 2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the website's photo and the actual item could be slightly different. We offer you wh.Power-off status, press and hold the left button access the power, the display starts flashing, release the left button. We'd like to settle any problem in a friendly manner. Load Regulation S(I): ≠¤0.8%.
