FAQ
Q: What is the working principle of a closed-loop Hall effect sensor?
A: A closed-loop Hall effect sensor 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, bringing the net magnetic flux in the core to zero. The compensation current is proportional to the measured current, providing high-accuracy, low-temperature-drift measurement results.
Q: What does a turns ratio of 1:1200 mean?
A: A turns ratio of 1:1200 means the ratio of primary current to secondary compensation current is 1:1200. For example, a 100A primary current corresponds to approximately 83.3mA secondary compensation current, which is converted to a ±0.625V voltage output through the built-in resistor.
Q: What new energy applications is this product suitable for?
A: This product is suitable for photovoltaic current sensing, new energy combiner box measurement, wind power current sensing, EV charging equipment current sensing, and hybrid battery pack current sensing in the new energy field.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
