Power Supplies

If there’s one thing that all electronics have in common, from big transformers to small transistors, it’s that they all require a power source to operate. Of course, some electronics do get their power from other sources like heat, vibration and light, but for non-specialised electronics, you’re going to need a reliable PSU for your projects.

 This is a collection of good Power Supply Units that we’ve sourced from various suppliers, and it includes both cheap (but reliable) basic AC/DC adapters all the way through to world-renowned PSU’s from Mean Well. They offer a relatively simple way to deliver the power your project needs, and are rated from 5V DC up to 48V DC, with some even extending beyond this for lab tests and serious prototyping.

If you need a quick and easy way to power up your Arduino boards, are looking for replacement power supplies for larger machines like 3D Printers, or are finally getting yourself a beefy Lab PSU for prototyping and building custom projects, then this is the perfect place to start. And of course, if you want to modify or customise your PSU further, be sure to also take a look through our Voltage Regulators Section, which allow you to buck, boost and fine-tune whatever voltage and current ratings you need.
