ACS758 MCU-758 Current Module Linear Hall Current Sensor ACS758LCB-100B-PFF-T Current Detection 3-5V Environmental Protection

Description:

The MCU-758 ACS758LCB-100B-PFF-T Hall Current Sensor Module is a high-precision, bidirectional current sensing module based on the Allegro ACS758 Hall-effect IC. It is designed to measure both AC and DC currents up to ±100A with excellent accuracy and electrical isolation.

This module uses Hall-effect technology, allowing non-intrusive current measurement without direct electrical contact with the measured circuit. It provides a ratiometric analog voltage output proportional to the current flowing through the conductor.

It is widely used in applications such as motor control, power monitoring, inverters, battery management systems, and overcurrent protection circuits.
