ARU-B100-D250/SP3

The ARU series is designed for outdoor installation, equipped with flexible and openable Rogowski coils. The transducer measures the true RMS value of AC current with very good accuracy. Perfect Loop technology significantly reduces measurement error caused by the position of the measured conductor and other nearby conductors. ARU Rogowski coils are intended for industrial implementation and smart grid technology.

NOTE! The ARU series cooperates with a dedicated digital AI-PUML Integrator which ensures dynamic operating range, accuracy, and application universality.
