CSNV1500N-156 is a CSNV1500 series, closed-loop current sensor. It is a hall-effect current sensor that uses Honeywell's patented technology to bring the enhanced combination of performance and reliability. This sensor is nonintrusive and electrically isolated from the monitored circuit. This ensures a simple and reliable structure without loss of power to the monitored circuit. It is rated for a primary current measurement range of ±1500A dc. This device is calibrated and temperature compensated for improved accuracy using multi-point temperature characterization. It is used in applications such as current measurement for battery management systems in electrified vehicles (EV, HEV, PHEV, BEV), current leakage detection and fault isolation in charging systems, current measurement in energy storage systems, fault detection in heavy industrial equipment.
