PX2-DATUBE
This board is a simple port of Allegro's ±30 A ACS712T ELC-5B Hall effect based linear current sensor. This version accepts a bidirectional current input up to 30 A in magnitude and outputs a proportional analog voltage centered at Vcc/2 with a typical error of ±5%. Its output is analog (66 mV/A).
- Designed for bidirectional input current from -30 A to +30 A (but the robust sensor IC can withstand five times the current).
- The internal resistance of the conductor path is typically 1.2 mΩ.
- The use of a Hall effect sensor means that the IC has the ability to provide electrical isolation (up to 2.1 kV RMS) from the current path to the electronics of the sensor, which means that the sensor can be placed anywhere in the current path and used in applications that require electrical isolation.
- 80 kHz bandwidth.
- Good accuracy and reliability: factory calibration results in a typical total output error of ±5% at room temperature, the output offset voltage is extremely stable and the sensor has no magnetic hysteresis.
- Operating temperature range from -40°C to 85°C.
