Pulse Electronics Rogowski RC01/03/05 Coil Current Sensors are available in 3 different sizes with a wide dynamic current ranging from 1A to 2500A. These sensors feature up to 50kHz bandwidth, 100mV/kA to 600mV/kA sensitivity range, <0.03 degree at 50Hz/60Hz phase error, and meet ANSI C12.20 accuracy class 1.0. The RC01/03/05 sensors also feature low-temperature dependency, immune to external AC magnetic fields and DC current. These sensors are ideal for measuring and billing applications for alternating current such as smart grids and smart metering.
