The CTA5000 and CTA10000 are ultra-high-accuracy fluxgate current transducers for very large currents. The CTA5000 measures 5000 A with accuracy up to 7 ppm and 50 kHz bandwidth; the CTA10000 measures 10000 A with accuracy up to 9 ppm and 20 kHz bandwidth.

A selector switch gives either a current output (4 mm banana sockets) or a voltage output (BNC). Fluxgate technology provides excellent linearity, very low DC offset and temperature drift, low insertion loss and strong interference immunity for industrial, medical and laboratory use.
