 		 #98083 - maybe this is what a "DC current transfo
Responding to: ???'s previous message
maybe so,mething like this is what a "DC current transformer" is (Frequency Range: DC - 4 KHz) http://www.crmagnetics.com/newprod/P...ame=CR5410

If a hall-effect solultion (the OP want to measure current although voltage is specified) this would be a very safe way.
