Heralded as the highest accuracy current transducer available, the ITL 900 current transducer measures DC, AC, and pulsed currents up to ±900A. It provides a linearity error of less than or equal to 3 ppm over an operating temperature range of +10ºC to +50ºC, an offset stability of less than 0.5 ppm over four hours, and an offset current temperature coefficient of less than 0.3 ppm/ºK . Other features include a measurement bandwidth of more than 200 kHz (-3 dB), negligible self-magnetization, a current overload capability, and galvanic isolation between the high-power primary circuit and the electronic secondary circuit.
