The bipolar TOPACC-HC Zero-flux™ system is a high precision DC current measuring system, based on the zero-flux principle, specially designed for extremely high DC currents up to 30 kA. This with a linearity better than 2.5 ppm. The system has many standard features such as automatic reset after overload, zero-current detection and uninterrupted operation through short power failures. The unique system is mainly used as control/measuring device in high performance power supplies and amplifiers, as a secondary DC standard reference, as a testing device or as a calibrating instrument. Applications include nuclear research projects, plasma physics experiments, applied scientific research, industry and industrial calibration workshops.
