Description
This large carrier board for the Allegro ACS37200LLXTR-150B3 Hall-effect current sensor measures bidirectional currents up to ±150 A and outputs them as an analog voltage. The current path is galvanically isolated from the sensor electronics, allowing the sensor to be installed anywhere in the current path. The large version with a 6-layer printed circuit board provides space for thick wires and ring cable lugs.
