Document 131 Current Sensors – D18xx, CS1xxx 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. They come in a molded version (CS1xxx Series) or encapsulated model (D18xx Series). Coilcraft Designer’s Kit P403 contains samples of the CS1050, CS1100 and CS1200 sensors, current transformer versions with equivalent ratings, plus two 50/60 Hz current sensors.
