Product: Buck Converter,DC 5-23V to 0-16.5V Buck Boost Converter Adjustable Voltage Regulator Setp Down Power Supply Module
Brand: IS
Color: 5-23V to 0-16.5V
Icstation mini digital dc-dc voltage regultor module is equipped with STC LCD screen display the output voltage and current with input polarity reverse protection. On-board tactile push button to regulate the output voltage better than the potentiometer. Come along with the acrylic,once assembled it will turn into a portable digital voltmeter also protect the module.

Specifications:
Input voltage: 5-23V 
Output voltage: 0-16.5V
Mini input output voltage difference: 1V 
Maximum Output current: 3A (suggest 2A during use, over 2A need the heatsink)
Display Accuracy: 1% 
Maximum Conversion Efficiency: 95% 
Load Regulation S(I) ≤0.8%
Voltage Regulation S (u) ≤0.8%
LCD Display Resolutio: 0.01
Module Size: 62*44*18 mm

Package Included:1X DC Step Down Power Supply

Voltage Calibration:
In the power off situation, press the left button but do not release then connect the power supply, the screen will flash, release the left button, use the multimeter to measure the output voltage, at the same time press the left or right button to regulate the output voltage close to the 5V (4.98-5.02 is better) which display on the multimeter but regardless of the module display. Then power off the module.
