开云体育I used DipTrace and I just uploaded the original file to the files section here under “K9HZ Projects’.? I believe KiCAD will also read DipTrace files (???) and you can make boards in that tool too. ? ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ ?

If I wranted to build a circuit like this one is there a software to help me layout a perfboard for the circuit.? I have LTSpice but I don't see anything to layout a perf board in it. It just may be that I don't know where that feature is in the software. |
开云体育Nope.? Works as designed.? Build it and try it.? Picture of my prototype is attached.? You will identify the Set-Reset transistors as a simple transistor version of an RS flip-flop. ? ? ? ?

开云体育To be clear, the SCRs trigger the RS flip-flop into the RESET (FAULT) state and it stays in reset until the fault condition presented by the SCR has been cleared.? THEN and only then can you SET the flip-flop (NORMAL) such that power is reapplied through U2. ? ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ ?
