[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 3V to 40V ( Input Voltage Must 1.5V Higher Than Output Voltage or More, this is a step-down module, the input voltage is higher than the required output voltage. )
[Output Voltage]DC 1.5V to 35V voltage is continuously adjustable, high efficiency (maximum 92%) of the maximum output current of 3A. (Do not reverse the input and output interface.)
[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)
[Applications]LM2596S module widely use for DIY mobile power, monitor power supply, power buggies, vehicle power supply communications equipment supply, etc. Note: Keep output under 2A (or 15W), and use a heat sink when for a long time working
