Based on Allegro’s ACS 712 current sensor IC, mounted on a small PCB board allows easy installation for measuring AC and DC current.ACS712 datasheet features IC as a fully integrated effective Linear Current Sensor IC based on Hall Effect.
The IC is SOIC8 packaged with SMD mounted on a compact board moduleproviding economical and precise solutions for AC or DC current sensing for max 5A current measurement with an operational supply of 5V DC.
ACS712-5A ensures the device safety standards by incorporating thick copper conductor on the input side for protection from the 5x time’s overcurrent conditions. Terminals are electrically isolated with no use of any costly isolation techniques makesACS712 current sensor IC’s best suited for the application in motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
For measurement, the device can be plugged to measure both AC and DC voltage at its input and its output which is linear with respect to the measured input shows linearly defined analog voltage on the output. The device has zero magnetic hysteresis and extremely stable offset voltage.
