Details:
The magnetic flux generated by the primary current gathers in the magnetic circuit and is detected by the Hall element at the air gap, inducing a voltage signal. After amplification by the op amp circuit, the voltage signal output by the sensor is convenient for sampling and processing by the back-end circuitry. This voltage signal is linearly related to the primary current and accurately reflects changes in the primary current.
Open-loop current sensors are characterized by their small size, simple structure, strong overload capacity, light weight, and low power consumption.

Recommended Applications:
UPS, photovoltaic inverters, combiner boxes, switching power supplies, frequency converters, etc.
