Product Overview

This breakout module incorporates a linear ACS712ELCTR-20A-T current sensor utilizing the Hall Effect, delivering accurate current measurements for both AC and DC signals. The ACS712ELCTR-20A-T generates an analog voltage output signal, exhibiting a linear correlation with the detected current. To operate, the breakout board necessitates a 5VDC power source. One notable benefit of employing a Hall effect sensor lies in the electrical isolation between the circuit under observation and the circuit responsible for interpreting the sensor data.

Please Note: Although the chip itself is rated for up to 2.1kV (RMS) of isolation, the board has not been designed for such high voltage applications.

The ACS712 20A Hall-Effect current sensor breakout with flap cover connector integrates the ACS712ELCTR-20A-T IC, which is a high-performance current sensor IC designed for accurate and reliable current sensing applications. The sensor breakout is capable of measuring up to 20 amps of current with an accuracy of +-1.5%, making it ideal for a wide range of applications, including motor control, power management, and energy monitoring. The sensor uses the Hall-Effect principle to generate a voltage across a conductor when a magnetic field is applied perpendicular to the current flow, which is then amplified by the ACS712ELCTR-20A-T IC. The IC also features a low-offset, low-drift, and high-bandwidth, ensuring accurate and stable measurements over time. The flap cover connector makes it easy to connect and disconnect the sensor from the circuit, and it also protects the sensor from dust and other environmental contaminants.

The ACS712 20A Hall-Effect current sensor breakout with flap cover connector integrated with the ACS712ELCTR-20A-T IC is a highly versatile and reliable sensor that is suitable for a wide range of current sensing applications.
