Simple Adjustable Voltage Power Supply
myminifactory
I'm always scouring through my collection of parts pins to find the perfect power supply so I decided to purchase a mini buck converter module to build a variable voltage power supply. I linked this device to a 31.5 VDC laptop power adapter and now I can adjust the output voltage to whatever I require. Specs: Input Voltage: DC 5~40V Output Voltage: 1.25V~37V (continuously adjustable, the input voltage must be at least 1V higher than the output voltage) Output Current: 2A (normal and stable), 3A Max. Under $10, DROK Brand Voltage Switching Regulator on Amazon: http://bitly.com/1NoRCQx (Make sure to choose the option that features an LED display & heatsink!)
