ACS724 Current Sensor Carrier 0A to 30A SF_Wire 25" (6 mm)This board is a simple carrier of Allegro's unidirectional 30A ACS724LLCTR 30AU Hall effect based linear current sensor, which offers a low resistance (~1. 2 m) current path and electrical isolation up to 2. 4 kV RMS. This version accepts a unidirectional current input up to 30 A and outputs a proportional analog voltage ( 133 mV A ) that measures 500 mV when the input current is zero. The typical output error is 0. 7%. It operates from 4. 5 V to 5. 5
