Re: Measuring DC current.


"TheM"

What's the easiest and relatively cheap way of measuring
high side DC current (0-30/50A, say 10% accuracy).

Preferably without using any drop resistors. I found hall sensors,
any advice from users of these?

It has to be isolated (can't insert anything into ground loop)
and the output would go to AVR so some processing can happen
there, if needed.


** Non contact, DC current sense with no resistive drop ?

The ONLY way is to use a Hall effect transducer.

LEM Heme and Honeywell make nice ones.

I can vouch for them.
