I am looking for a current sense device similar to an LEM module.  I would like to put two wires through it to measure the difference in current.  There is both a DC and an AC (120Hz) component to the current so it will need to handle both.  We would like to measure an rms current of 0.5 to 1 amp with peak currents around 3.  I am currently looking at the LEM module CT 0.4-P http://www.lem.com/docs/products/ct_e.pdf Do you have anything similar?
Some more details
I need an rms value, whether the rms value comes directly from a transducer or if we deduce it from the isolated side of the transducer I don't care. 
 
I would prefer to have an adjustable trip point in the field for some customers 100mA to 1Amp but this is not a requirement at this point.  It is more important for us to get this into production but if you have something like this that would be great!  In other words if there is something that is cheap and available that trips at say 300mA rms I think that would be acceptable at this point.
Cheers
