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.\n\nThis 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.\n\nKey Features\n\n\n±50A Bidirectional Range – Measures high current flowing in both directions\n\n40 mV/A Sensitivity – Proportional analogue output centred at 2.5V\n\nHigh Isolation – Electrical isolation up to 2.4 kV RMS\n\nLow Resistance – ~1.2 mΩ current path for minimal circuit impact\n\nHigh Accuracy – Typical error of ±0.8%\n\nCompact Carrier Board – Includes bypass capacitors, ready to use\n\n\nSpecifications\n\n\nSensor IC: ACS724LLCTR-50AB\n\nSupply Voltage: 4.5V – 5.5V DC\n\nCurrent Range: -50A to +50A\n\nSensitivity: 40 mV/A\n\nOutput Voltage: 2.5V at 0A (ratiometric)\n\nIsolation: 2.4 kV RMS\n\nPath Resistance: ~1.2 mΩ\n\nTypical Error: ±0.8%\n\n\nAlso Available\n\nACS711EX Current Sensor Carrier – ±31A\nACS714 Current Sensor Carrier – ±5A\nACS712 Current Sensor – 5A\nACS712 Current Sensor – 20A\nGravity: Analog Current Sensor 50A (AC/DC) V2\n\n\nIdeal For\n\nHigh-current motor control and monitoring\nIndustrial power supply monitoring\nElectric vehicle battery management\nSolar inverter current sensing\nOver-current protection in high-power circuits\n\n\nPackage Contents\n\n1× ACS724 Current Sensor Carrier Board (±50A)\n","vendor":"Pololu","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":5048,"title":"Default Title","sku":"PL-4049","price":29.05,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
