Closed loop Fluxgate current transducers for very high current precision measurement. 2000 to 4000 ARMS with a 102mm diameter aperture, 14 KVRMS galvanic isolation, 0.1µs response time, and DC to 80 kHz bandwidth in a panel-mount package with low temperature drift. Current consumption is very low at 300mA; analogue current output; reduced size relative to competing solutions at this current level.

Applied in railway fixed installations and onboard locomotives, high-power industrial systems, and large-scale energy conversion equipment where galvanic isolation and high accuracy must be maintained at multi-kiloamp current levels.
