This is just a question of curiosity. But why do you think in your opinions Galvanic Isolators cost up to $300 or so dollars(for some), cheapest I've seen was $150? To my understanding, they seem like simple enough devices, in essence, a couple of diodes(which you can find millions of, in a CPU, on Ebay, for $10), with a few other throwins....certainly no more complicated than a VHF radio
. Is it one of those things where people are like "Well...if you don't buy one of these, you could pay thousands of dollars in repairs
, so it's worth $200 in the long run!"?
This is starting to sound more and more like a DIY
, I'll just have to figure out what size of rectifiers is used in 'em. Thanks for any enlightenment on this subject.
