DC-DC Adjustable Step-down Power Supply Buck Module Voltage Current LCD Display
Product Description
Specification:
Input voltage: 4.75 ~ 23V, maximum 23V, recommended to use within 20V. (Input voltage must be higher than the output voltage 1.5V above, make sure that the positive and negative input voltage and then access, reverse may damage the module components are responsible for this reason) Output voltage: 0V ~ 15V continuously adjustable, automatically save the last set voltage. Output Current: 3A MAX (2A long time use). Accuracy of 1, minimum display 0.01, the unit is A, 10mA or less will not be displayed. High conversion efficiency: 96 MAX (efficiency and input and output voltage, current, pressure related) Size: approx. 55 x 35 x 18 mm
Calibration instructions:
The module with the calibration function without worrying about measurements show allowed to question, normal delivery after previous calibration will be issued, allowed or if you find that the display show the value stuck left and right buttons can not mobilize voltage, you can use the following method of calibration The calibration method: the absence of power, access to power and hold the left button, the display starts flashing, release the left button, the output terminal voltage measured with a multimeter, if the measured voltage is greater than 5V press the Left reduced to 5V, If the voltage is less than 5V press the right to increase to 5V, the LCD screen shows the voltage of 5V, sometimes shows 4.99, after adjusting off the power, the calibration is complete.
Module Benefits:
Using the STN liquid crystal display screen, can display voltage and current, blue and white, wide angle any angle is very clear, the use of digital tube display spike similar products, ordinary digital works for some time will be a bad segment, this product does not exist such a problem. The first key tune voltage, left to reduce the voltage, the right to the applied voltage, single-press trimming 0.04V voltage, long press and hold 1S can quickly adjust voltage and can withstand thousands of times pressed; more convenient than comparable potentiometer Surge Shortcut.
Package included:
1 x Step Down Module (without shell)
