Notes: Product specifications can be customized
Q: What is the working principle of the zero-flux balance method?
A: The zero-flux balance method (closed-loop Hall effect) uses a Hall element to detect the magnetic field generated by the measured current. The output signal drives a compensation coil to generate an opposing magnetic field, keeping the net magnetic flux in the core at zero. The compensation current is proportional to the measured current, providing high-accuracy, low-temperature-drift measurement results.
Q3: Does this product support customisation?
A: Yes. Customisation of different rated input currents and output current specifications is available to meet diverse application requirements. Please contact our sales team for details.
Q: What types of current can this sensor measure?
A: It can accurately measure DC, AC, and pulse currents, suitable for various complex current waveform measurement requirements.
