An old pc power supply unit makes an excellent and cheap bench top power supply for the electronics constructor.

Digital bench power supply schematic.

This electronic project can serve as a your lab power supply to test and power your experiments. The power supply unit uses switching regulators to maintain a constant supply with good regulation and short circuit protection cause the unit to shutdown and be re powered immediately if something goes wrong. Many ideas of 12v and 5v dual power supply circuit diagram at 3a max. The post details how to design and build a good work bench power supply circuit right from the basic design to the reasonably sophisticated power supply having extended features.

Digital dc regulator if you are looking for 5v dc power supply for the digital. And last pics are reserved solely for the start of this article the digital bench powersupply itself. Simple dc regulators 12v 15v 30v. 5v power supplies digital power supplies.

Designing a workbench power supply is indispensable. A lot of standard models have positive negative and ground voltage level output jacks for exactly this reason. Yes the last picture is the very old photo of my first power supply constructed a few years ago. With the variable supply feature it is easy to control and deliver voltage and current to the load.

A lot of 6v supply diagrams. Build a bench top lab power supply that is capable of delivering 0 to 50 volts and 0 to 5 amp or a to the load. 1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups.
