Railway current sensors
The ITC product family is designed for measuring DC, AC, and pulse currents with high accuracy and non-invasive methods, capable of handling currents up to 4000 ARMS with high galvanic isolation (isolation test voltage: 14 KVRMS / 50Hz / 1 min).
These current sensors feature a 102 mm diameter aperture, very low current consumption at 300 mA, a fast response time of 0.1 µs, and a large bandwidth of up to 80 kHz (3dB). Additionally, they exhibit low temperature drift of accuracy.
The ITC sensors provide an analogue current output, reduced size, and low power losses, making them highly efficient.
Designed for panel mounting, these sensors utilize closed loop fluxgate technology, ensuring reliable performance specifically for traction and trackside applications.
