Key Features
- 【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)
