Acs711lc Current Sensor Carrier -25A To +25A (Polulu-USA)

This board is a simple carrier of Allegro’s ±25A ACS711 Hall effect-based linear current sensor with over current fault output, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 100 V. This version accepts a bidirectional current input with a magnitude up to 25 A and outputs a proportional analog voltage centered at Vcc/2 with a typical error of ±5%. It operates from 3 V to 5.5 V, so it can interface directly to both 3.3 V and 5V systems. This current sensor is a carrier board or breakout board for Allegro’s ACS711KLCTR-25AB-T Hall effect-based linear current sensor with over current fault output.

Features
