Overview and Specifications:
This current sensor is a carrier board or breakout board for ACS714LLCTR-05B-T Hall effect-based linear current sensor;The sensor operates at 5V and has an output sensitivity of 185 mV/A. The board ships fully populated with its SMD components, including the ACS714, as shown in the product picture.
The following list details some of the sensor's key features:
Designed for bidirectional input current from -20A to 20 A (though the robust sensor IC can survive up to five times the overcurrent condition).
Conductive path internal resistance is typically 1.2 mΩ, and the PCB is made with 2-oz copper, so very little power is lost in the board.
Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor's electronics (up to 2.1 kV RMS), which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
80 kHz bandwidth that can optionally be decreased by adding a capacitor across the board pins marked "filter"
High accuracy and reliability: typical total output error of ±1.5% at room temperature with factory calibration, an extremely stable output offset voltage, and almost zero magnetic hysteresis.
Automotive-grade operating temperature range of -40°C to 150°C
