DC to DC Step-down Power Supply Module w/ LCD Display - Light Blue
Features: - Adopt STN LCD screen£¬ it can display voltage and current at the same time. - Creative design with button to adjust voltage£¬ left minus and right plus. - Convenient to use with terminals - Converter type: DC-DC - Input voltage: 5-23V (Advice you can operate within 20V voltage to input anti-reverse. Remember the input voltage must be higher over 1V than output voltage) - Output voltage: 0V-16.5V(Continuously adjustable) - Maximunm current: 3A (Advice you had better operate within 2A£¬ or it will spread out too much heat) - High conversion efficiency: 95% - Load Regulation S(I): ≤0.8% - Voltage Regulation S(U): ≤0.8% - Mainboard Demension: 50mm x 30mm x 12mm Calibration method: Under power off situation£¬ Holdind left button and power the supply£¬when the display begin flashing£¬ release left button£¬ with multimeter measuring the output voltage£¬ by press the left and right button £¬adjust the multimeter measuring voltage near 5V£¬ such as 5.00V £¬4.98V or 5.02V is ok too£¬at this situation£¬please ignore the displaying on this item. After adjustment£¬please power off it and then power to it again£¬ then the calibration is completed. Errors can be calibrated in 0.04V£¬ if the error is greater£¬ you can try to calibrate it again.
