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 3.0V to 40V (input voltage must be 1.5V higher than the output voltage, or more can not be boosted).
Output Voltage: DC 1.5V to 35V voltage is continuously adjustable, high efficiency and maximum output current is 3A.
Mini Size: 43.7 * 21.6 * 14.1 mm (with potentiometer).
Easy to DIY: 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 15-20 turns CCW before the voltage starts ramping down).
