Transient Peak Sensing Hall Effect Current Transformer
Product Description
PRODUCT OVERVIEW
The sensor works on the principle of direct measurement Hall detection. The magnetic flux generated by the primary current is gathered in the magnetic circuit, and the Hall voltage signal is detected by the Hall device. After amplification by the amplifier, the voltage signal accurately reflects the primary current.
