HTC Series
Compact current transducers for AC and DC currents from 1000A to 3000A nominal.
HTC - Traction current sensors
The HTC current sensor family is meticulously crafted for the accurate measurement of DC, AC, or pulsed currents, all while ensuring galvanic isolation between the primary and secondary circuits.
Members of the HTC family function effectively with a bipolar power supply ranging from +/- 15V. They deliver an instantaneous voltage output spanning of +/- 10V and boast a bandwidth extending up to DC 10 KHz.
These current sensors feature a 40 mm diameter aperture for current measurement and are based on open-loop Hall effect technology, making them exceptionally well-suited for a diverse range of traction applications within the railway sector.
