Re: Precipitator power supplies?

... Of course, the diode as you may or may not know is seeing a higher peak voltage than the max rated voltage for the supply (for any AC powered device) so these diodes must be rated for the higher voltage with some safety factor. As for grounding, that is an issue but that depends on the supply ...

... this would be, but I like it! incidentally, capacitors will surely have safety factor so you don't actually know the voltage cap. Try an oil burner ignition transformer. They are basically like an NST. While ...
