The CN2A PB01 SERIES is a closed-loop (compensated) current sensor utilizing Hall Effect technology for the electronic measurement of DC, AC, and pulsed voltages. It provides galvanic separation between the primary and secondary circuits, offering high accuracy, very good linearity, and low offset drift over temperature. This sensor is designed for applications requiring reliable current measurement with safety standards compliance.
