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. ... This power supply circuit has a over-current ...

Then IC’s like the LM7805 series of voltage regulators changed everything. No longer were system designers required to spend their time designing the power supply section also. These modern IC’s even ...

Protecting a power supply and its load from each other’s faults requires components and functions such as the fuse, undervoltage lockout, crowbars, and clamps. Power protection is like insurance ...

Up to four load circuits per module can be protected. Additional electronic diagnostic modules can be connected to the power supply if the application requires the protection of more circuits. The new ...

For power-supply controllers with an external soft-start pin, however, a simple circuit can be added to convert its non-latching fault protection into one with latched protection.

[C] just recently put together a RepRap. Not wanting to spend the money on a dedicated power supply, he looked around for a cheaper solution and found one in an off-the-shelf ATX computer power sup… ...
