The ACS758KCB-150B-PFF-T is a high-performance Hall Effect-based current sensor IC designed for accurate measurement of both AC and DC currents up to ±150A. It offers excellent isolation and safety for high-voltage applications without the need for opto-isolators or complex insulation methods.

With its factory-calibrated design, ultralow conductor resistance (100 µΩ), and integrated shield for noise immunity, this sensor delivers precise, stable, and low-noise current measurements, making it ideal for industrial, automotive, and power electronics applications in Bangladesh.

The ACS758 is built with a monolithic Hall IC, ensuring long-term reliability. Its galvanic isolation enables safe high-side current sensing in inverters, motor control, battery monitoring, UPS, and renewable energy systems. With a 120 kHz bandwidth, 3 µs response time, and ratiometric output proportional to supply voltage, it provides fast, accurate, and temperature-stable current readings.
