CT-400

The CT-400 is a 0-FLUCS DC current transducer (DCCT) from ELS Instruments (formerly CAEN ELS) for high-precision, isolated measurement of bipolar currents up to ±400 A. It comes in current-output and voltage-output versions for power supply regulation and current monitoring. ProDigitek supplies the CT-400 in Australia.
