Adjustable power supply
Description
This is an adjustable power supply box with two voltage/amperes gauges. In the picture are missing the 5vdc output female jacks. Power supply is 220v or 110v, outputs as follow: 5Vdc USB port 12Vdc fixed female jacks Adjustable voltage jacks 0-12Vdc female jacks 5Vdc female jacks The fixed 12Vdc is maximum 2,5A (this depends on main switching board). For higher currents or voltages you need to replace the switching power supply. The voltage and current regulator is good up to 32V 5A. The Adjustable 0-12Vdc has potentiometers to adjust voltage and current ( resolution 0.01V and 0.01A ). One of the gauges displays the voltage and current output of the main switching power supply. The second one has selectable inputs. To select inputs there are two 5 positions switches, so you can have voltage and current input selection.

These are just links to selected eBay and Aliexpress items, where I normally buy spare parts and materials for my printer, prices are excellent and products are good. If you buy something from here you will support me a little bit to make these projects. <a target="_blank" href="http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=9&pub=5575414000&toolid=10001&campid=5338353127&customid=PLA&icep_uq=pla+filament+1kg&icep_sellerId=&icep_ex_kw=&icep_sortBy=12&icep_catId=&icep_minPrice=&icep_maxPrice=&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg">1Kg PLA Filament -
