Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

This ac to dc power supply can output 5A in continous operation and 12A peak current. This kind of dc power supplies uses a PCB so you can use two case types for IC1, TO-220 or TO-3. The regulation of ...

A Power Supply Circuit design using Altium Designer This is a voltage regulator circuit that uses a 7805 voltage regulator to provide a steady 5V output. Here's a breakdown of the components and their ...

For the Universal Sensor Interface (USI) project, I needed a power supply capable of powering op-amps with both +12V and -12V rails as well as +5V and might as well have +3.3V too. I had previously ...

If PSU's and desktops were only 12v, it would mean a 500w psu should actually have atleast 500w of usable power. <BR><BR> I don't know very much about electronics though, I could be mistaken.
