  • Measures unidirectional and bidirectional currents

The Pololu ACS72981KLRATR-150U5 Current Sensor Large Carrier 0A to 150A, 5V is a Hall effect-based, electrically isolated current sensor designed for nominal 5 V operation. It features a low-resistance current path and a high bandwidth of 250 kHz, ensuring fast response times. This sensor is suitable for applications requiring electrical isolation and can measure unidirectional input currents from 0 A to 150 A. The sensor outputs a ratiometric analog voltage proportional to the input current, with integrated digital temperature compensation for improved accuracy across the operating temperature range.

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