NC Power Supply Module/Charger DC 5~23V to 0~16.5V 3A Adjustable Buck Voltage Regulator/Adapter/Driver Module With LCD Voltmeter/Ammeter/Capacity Indicator

● Our module display used STN LCD screen, blue background and white digit, can be clearly seen in any angle.
● The large screen displays the voltage and current simultaneously, clearly visible.
● With two amazing button adjusting the voltage, which can withstand thousands of times press, one for reducing voltage, one for increasing voltage; simply press to fine adjust 0.04V, long press 1s for quickly adjusting.    Compared to similar potentiometer regulators, it's more convenient and easy to use.
● Our step-down module adopted imported MP2304 chip; high efficiency, low heat.
● With terminal blocks, designed to conveniently use even without no soldering iron.

● Input voltage: DC 5~23V, recommend the use of within 20V. (Input voltage must be 1V higher than the output voltage.)
● Output voltage: DC 0~16.5V, continuously adjustable.(Automatically saves the last set voltage.)
● Output current: 3A Peak, recommend the use of within 2A. (Over 2A, please enhance heat dissipation.)
● Accuracy: 1%
● High conversion efficiency: up to 95%
● Load regulation: S (I) ≤0.8%
● Voltage regulation: S (u) ≤0.8%
● Size: 62 x 44 x 18mm

• The module has calibration function, no need to worry if the measurement is not accurate.
• If you find that the measuring values are not accurate or values are stuck, and left and right buttons can not adjust  voltage, please do as follow:

● First, in the case of power off, press and hold the left button and don't access to power, then the display starts flashing, release the button.
● Next, measure the output voltage with a multimeter and press the left and right button to adjust the value until the multimeter displays close to 5V, such as 4.98V, 5.02V.
● Finally, access to power, then the calibration is complete. Error can be less than 0.04V, if the error is larger, you can try again.
