I am quite new to electronic circuits. I have just completed my first circuit that works... WaHooo. I need to ad a couple of features and can't seem to get understanding on making it happen.
I built the 12V 30Amp PSU as found **broken link removed** . Instead of using the LM7812C I used the LM350T. Needed to regulate between 2 & 5V and needed a full 30amps.
Today I found I could adjust over 35amps. I need to limit this to fold back or at least limit the total current output. I read up on the LM350T https://www.electro-tech-online.com/custompdfs/2005/10/LM150.pdf mfg data sheet web page on page 10 explains a precision Current Limiter. I am having trouble understanding how to tie in both the by pass transistors TIP2955 & LM350T to the discribed current regulation.
And as a second request: Is there a method to hook up a LED to indicate issues such as over current conditions should this happen?[[/url]
