DC-DC 6-30V To 7-32V Max 3A Adjustable Step-up Power Supply Module With Shell

Features:
With transparent acrylic shell, easy to read while protecting the module
Using LCD 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 0.05V voltage, press and hold more than 1 second to quickly adjust voltage.
Can withstand 100,000 presses; Compared with similar potentiometer voltage regulation more convenient and fast.
Only can be used as a step up converter, and input voltage should be >1V lower than output.

Calibration Description:
The module with a calibration function, do not worry about measuring and display is not accurate questions, when you find the display is not accurate or the display value always no changed, left and right keys can not adjust the voltage, then it need calibration.
 
Calibration Method:
In the case of no-load power, press and hold the left button to connect to the power supply, the display starts to flash, release the left button, measure the output voltage with a multimeter, press the left and right keys to adjust until the multimeter and LCD display the same output value. such as: When entering the module, the module LCD displays 18V, then the output is adjusted to 18V. after adjusting, cut off the power supply, and then access the power supply, the output voltage will show the default 24V or so. The error can be calibrated within 0.05V, if the error is greater, You can try to calibrate again.
 
Packing includes:
1pcs x Boost Regulator Power Supply Module
