5 Pack LM2596 DC to DC Buck Converter 3040V to 1535V Power Supply Step Down Module

Input DC 3 V to 40 V input voltage must be 15 V higher than the output voltage no boost lm2596 dcdc buck converter Output DC 15 V to 35 V voltage is continuously adjustable maximum output current is 3 A Steps connect to power source adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage The factory have tested these at max voltage so they are very high by default takes about 1520 turns CCW before the voltage starts ramping down LM2596 buck converter features all use SANYO solidstate capacitors 36 u thickening circuit boards highQ inductance with LED indicator output Quantity 5 pieces Size 45 20 14 mm
