AC/DC closed-loop (magnetic balance) Hall current sensor

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.

Installation Precautions

The sensor should be wired correctly, otherwise it may damage the internal components of the sensor

When the sensor is soldered to the circuit board, it needs to be soldered with a low-temperature soldering iron, and the time should not be too long, and secondly, the pins should not be squeezed by a large amount, otherwise the internal connection may be opened.
