Designed for use above 20 kHz, these sensors function as the secondaries of a current transformer. The conductor carrying the current to be measured is the “one turn primary.” Sensitivity can be set at 1 Volt per Ampere or at other desired values. It can also be doubled by looping the conductor through the hole twice. Applications include sensing branch circuit overload, switcher feedback, and detecting load drop or shutdown.
