Hi all,
Building a small uC board which is going to be used in a noisy industrial environment. I want to try and give my circuit some protection from possible spikes / emc interference. The board uses a 7805 regulator with decoupling caps and takes its power from a 12V switch mode power supply.
I was thinking of using a fuse and dummy diode and maybe a tranzorb on the input stage.
Do you think its necessary to add any additional filtering to the board. I assume most switch mode power supplies are reasonably clean and most of them seem to have good protection/safety features themselves
If anyone can provide some tips or experiences they have had with circuit protection i would love to hear from you.
thanks
