Document 131 Current Sensors D18xx, CS1xxx These sensors function as the secondaries of a current transformer.The conductor carrying the current to be measured is the “one turn primary.”Voltage per Ampere can be adjusted by varying the terminating resistor (see note 3). 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).
