U. Dreher Popular answer

If you can cope with the limited isolation, one of the current IC current sensors based on the Hall effect should apply very well:

* cheap

* quite precise

* easy to apply.

The Allegro ACS-72x may be the best known examples, but other manufacturers have similar offers.

Phil Denby

I recommend U. Dreher's reply, I have used them myself, and they are very simple to implement.
