Compact Hall-effect current sensors for 200 A and 300 A current ranges
22/12/2014 HARTING Ltd
HARTING has added two new high-current models to its range of Hall-effect current sensors. In addition to offering primary current measurements at up to 200 A and 300 A, respectively, the new models are only half the size and weight of previous versions. They also operate over a wider temperature range: from -40°C to +85°C, allowing them to be deployed in thermally critical applications.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%. They can measure both direct and alternating currents, as well as signals with complex waveforms, over a frequency range from 0 to 100 kHz. 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.
Typical applications are in photovoltaic inverters, frequency converters or power supplies for welding applications.
