ACS724 Current Sensor Carrier 0A to 20A

Pololu presents the ACS724 Current Sensor Carrier 0A to 20A, a simple yet efficient board carrier for Allegro's unidirectional 20A ACS724LLCTR-20AU Hall effect-based linear current sensor. The sensor is designed to offer a low-resistance current path of approximately 1.2 mΩ and electrical isolation that reaches up to 2.4 kV RMS. This version is capable of accepting a unidirectional current input up to 20 A and outputs a proportional analog voltage of 200 mV/A. Notably, the output measures 500 mV when the input current is zero, with a typical output error of ±0.7%. The sensor operates from 4.5 V to 5.5 V and is specifically designed for use in 5 V systems.The ACS724 Current Sensor Carrier is a versatile tool with a wide range of applications. It can be used in power management systems, overcurrent protection circuits, and battery chargers. The sensor's ability to output a proportional analog voltage makes it ideal for use in systems where current monitoring is crucial.Among the key benefits of this current sensor is its low-resistance current path, which ensures efficient operation and minimizes power loss. The electrical isolation of up to 2.4 kV RMS provides an added layer of safety, protecting your systems from potential electrical faults.The unique properties of the ACS724 Current Sensor Carrier include its unidirectional input capability of up to 20 A, and a proportional analog voltage output. This makes it a reliable and accurate tool for measuring current in your systems. Furthermore, its compatibility with 5 V systems makes it a versatile addition to your electronic components.
