Features:
This step-down voltage power module adopted MP2304 chip; 95% conversion efficiency, +/- 1% accuracy, low heat generated.
Clear and large LCD display, blue background and white digit, reading voltage and current at the same time.
Input voltage range is DC 5-23V, suggested voltage range is lower than 20V, Continuously adjustable output voltage 0-16.5V, input voltage should be 1V higher than output voltage.
Unique design, two amazing button for adjusting the voltage, one for reducing voltage, the other for increasing voltage, convenient for you to adjust voltage.
Designed with terminal blocks, you can connect the input and output by using a screwdriver, needn't any soldering work.
Specifications:
Input Voltage: 5V~23V, recommend the use of within 20V. (Input voltage must be 1V higher than the output voltage.)
Output Voltage: 0V~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 / 2.44 x 1.73 x 0.7"
Calibration:
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:
Calibration Method:
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.
