The new sensors use the closed-loop measurement principle, which provides a direct representation of the primary current with an accuracy of up to ±0.5 percent. They can measure both direct and alternating currents, as well as signals with complex waveforms, over a frequency range from 0 to 100kHz. A particular benefit of these devices is high resistance to interference from magnetic fields generated by external current-carrying conductors.
The sensors come in a range of standard sizes and their compact construction offers a high degree of freedom for integration into individual applications. They operate over a wide temperature range: from -40°C to +85°C, allowing them to be deployed in thermally critical applications.
