Product Description

The ACS758 50A Current Sensor Module is a precision Hall Effect current sensing module designed for accurate measurement of both AC and DC currents up to 50A. Built around the Allegro ACS758 sensor IC, it provides an analog voltage output proportional to the measured current while offering galvanic isolation between the current path and the control electronics.

This module is ideal for battery management systems, solar power monitoring, motor control, power supplies, electric vehicles, industrial automation, robotics, and energy monitoring applications. With its low-resistance current path, fast response time, and excellent noise immunity, it delivers reliable performance even in demanding environments.

Compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi (via ADC), and other microcontroller platforms, the ACS758 module is easy to integrate into embedded projects requiring accurate current measurement.
