[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display

【High Precision】The buck converter consists of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects..
【Input Voltage】DC 4V to 38V (input voltage must be 1.5V higher than the output voltage, no boost)..
【Output Voltage】DC 1.25V to 36V voltage is continuously adjustable, maximum output current is 5A..
【Mini Size】62*38*14 mm (with potentiometer). 2 sets included..
【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step-down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V).

Parameters: DROK buck converter input voltage range is DC 4-40V, adjustable output voltage range is DC 1.23-37V, max output current is 3A, conversion rate can up to 92%..
High Precision Potentiometer: the buck circuit adopts imported BI potentiometer, with high resolution, sensitivity, reliability..
Output Indicator: the volt transformer board is with a indicator light, which is green and the display is bright, clearly visible and not glare..
Safe Protection: the step down power supply module is designed with reverse connection protection, over current protection, overheat protection, short circuit protection..
Note: the dc-dc buck converter can work stably at 3A indoor (Test condition temperature is 29 ℃, and humidity is 50%). If it’s for long time work, it is recommended adding heat sink..
