ACS758LCB-050B 50A Linear Current Sensor Module
The ACS758LCB-050B 50A Linear Current Sensor Module is a high-accuracy Hall Effect current sensing module designed for measuring both AC and DC current up to ±50A while maintaining complete electrical isolation between the measured current and the output signal. Built around Allegro's trusted ACS758 sensor IC, this module delivers fast response time, excellent linearity, and low power loss.
Unlike traditional shunt resistor-based current measurement methods, the ACS758 uses Hall Effect technology, making it safer, more efficient, and suitable for high-current applications. It produces an analog voltage proportional to the measured current, allowing seamless integration with Arduino, ESP32, STM32, Raspberry Pi, PIC, AVR, and other microcontrollers.
This sensor module is widely used by Bangladeshi students, electronics engineers, robotics developers, EV enthusiasts, solar energy system designers, UPS manufacturers, battery management system (BMS) developers, and industrial automation professionals.
