Closed loop Fluxgate IT current transducers for high-current precision industrial measurement. 400 to 4000A with IP54 protection, 3 ppm linearity, and external clock synchronisation for multi-channel measurement systems requiring phase-coherent sampling. An LED and status output signal indicate normal operation and protection mode. The ITL 4000-S is specified for HVDC Voltage Source Converter (VSC) applications where current measurement accuracy directly affects transmission efficiency.

Applications include HVDC VSC systems, medium voltage power factor correction and active filters, high-power drive development and test, and any industrial application requiring precision current measurement above the IT Series’ 1000A ceiling.
