Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

Standard ATX power supplies aren't designed to turn on unless they are properly connected to a motherboard. This helps to ensure that they can't power up and damage computer components if the plug isn ...

If your computer is behaving strangely or randomly crashing, it can be hard to nail down the culprit. And as much as you don't want to believe it's the problem, testing your power supply should be ...

An additional push-button switch is normally required for the ATX Power Switch/Soft Power Switch signal, but you can do without it if you use this simple circuit. It is an artful design, but it has ...

The circuit of power supply for PC works with a mains voltage of 230VAC to produce an output of 13.8V at 5A due to rectification. This project came upon the modification of a PC switch mode power ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs ...

Simply put, designing a power supply is a major undertaking. After making your build vs. buy decision, you face a myriad of circuit choices—more than you probably realize. Building a power supply used ...
