I need to measure 2.5A (ac) and detect fault current. Currently I am using a Isolated Current Sensor with Overcurrent Detection ACS716KLATR-6BB-T Datasheet
I am using this part because space is the most important restraint, and of course next is cost. I need 3KV isolation as well.
My question is is there a smaller way to measure current and faults on the high side? Is there a smaller way to do this?
Working voltage is 100 - 277V (ac)
