  • Includes digital temperature compensation
  • Compatible with standard breadboards

The Pololu ACS72981ELRATR-200B3 Current Sensor Large Carrier -200A to +200A, 3.3V is a Hall effect-based, electrically isolated current sensor designed for nominal 3 V operation. It features a low-resistance current path and a high bandwidth of 250 kHz, providing fast response times for both AC and DC currents. The sensor outputs a ratiometric analog voltage proportional to the input current, with integrated digital temperature compensation for improved accuracy.

This large carrier version is suitable for applications requiring bidirectional current measurement from -200 A to +200 A. It is compatible with standard solderless breadboards and offers various connection options for integration into the current path.

Note: This product is intended for use below 30 V. Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns.
