## Description

The ACS724 Current Sensor Carrier provides a compact breakout for Allegro's ±50A ACS724LLCTR-50AB Hall effect-based linear current sensor. It offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS, making it suitable for high-current monitoring in motors, power supplies, and industrial applications. This bidirectional sensor accepts current up to ±50A and outputs a proportional analogue voltage centred at 2.5V, which can be read directly by an Arduino or other microcontroller. The carrier board includes bypass capacitors and is designed for use in 5V systems. Key Features ±50A Bidirectional Range – Measures high current flowing in both directions 40 mV/A Sensitivity – Proportional analogue output centred at 2.5V High Isolation – Electrical isolation up to 2.4 kV RMS Low Resistance – ~1.2 mΩ current path for minimal circuit impact High Accuracy – Typical error of ±0.8% Compact Carrier Board – Includes bypass capacitors, ready to use Specifications Sensor IC: ACS724LLCTR-50AB Supply Voltage: 4.5V – 5.5V DC Current Range: -50A to +50A Sensitivity: 40 mV/A Output Voltage: 2.5V at 0A (ratiometric) Isolation: 2.4 kV RMS Path Resistance: ~1.2 mΩ Typical Error: ±0.8% Also Available ACS711EX Current Sensor Carrier – ±31A ACS714 Current Sensor Carrier – ±5A ACS712 Current Sensor – 5A ACS712 Current Sensor – 20A Gravity: Analog Current Sensor 50A (AC/DC) V2 Ideal For High-current motor control and monitoring Industrial power supply monitoring Electric vehicle battery management Solar inverter current sensing Over-current protection in high-power circuits Package Contents 1× ACS724 Current Sensor Carrier Board (±50A)
