2pcs/lot DC-DC Step Down LED Driver Adjustable Constant Voltage Supply Module with CC CV IndicatorSold By exlene, Ships from China
Parameters: Input voltage : 5-30V Output voltage : 1.25V-26V ( input buck mode output is always lower than 2V above ) Output Current : 0.15A-2A adjustable Module size : 56 * 38 * 23mm ( L * W * H ...Read More…
Note: When working at full load module fever is severe, please pay attention to strengthening the heat! Constant voltage ripple: 50mV peak to peak ripple frequency 52Kh
Full load efficiency of 85% or soConstant current regulation point : with a multimeter current file directly shorted output regulation of the board to the left of precision potentiometers (CC) clockwise to increase and counterclockwise to decrease the output constant current constant point test can be displayed on the meter !
Constant output regulation : load connected to the output of the power supply board in the middle of adjusting precision potentiometer with a multimeter voltage profile (CV) clockwise to increase and counterclockwise to decrease the voltage output voltage output voltage output at this time can be displayed on the meter ! Normally takes about 3V regulator working pressure above !
