ACS724 Current Sensor Carrier -50A to +50A

This board serves as a straightforward carrier for Allegro's bidirectional ±50A ACS724LLCTR-50AB Hall effect-based linear current sensor. It features a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version can accept a bidirectional current input up to 50 A and outputs a proportional analog voltage (40 mV/A) centered at 2.5 V with a typical error of ±0.8%. Operating from 4.5 V to 5.5 V, it's ideal for 5 V systems.

Using this current sensor carrier is easy. First, make sure your system operates within the 4.5 - 5.5 V voltage range as this sensor is designed for 5 V systems. Connect the bidirectional current input to the sensor, with a maximum magnitude of 50 A. The sensor will then output a proportional analog voltage centered at 2.5 V. When handling, avoid exposing it to high - voltage sources beyond its 2.4 kV RMS electrical isolation limit. For maintenance, keep it in a dry and clean environment. If you notice any abnormal output voltages, check the connections and ensure the input current is within the specified range.
