ACS714 Current Sensor Carrier -5 to +5A

This board is a simple carrier of Allegro’s ±5A ACS714 Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.1 kV RMS. This version accepts a bidirectional current input with a magnitude up to 5 A and outputs a proportional analog voltage (185 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 to 5.5 V and is intended for use in 5 V systems.

ACS715 Current Sensor Carrier 0 to 30A
Pololu item #: 1186
Price: $9.95
Quantity:

ACS715 Current Sensor Carrier 0 to 30A

This board is a simple carrier of Allegro’s 30A ACS715 Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.1 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 ±1.5%. It operates from 4.5 to 5.5 V and is intended for use in 5 V systems.

ACS714 Current Sensor Carrier -30 to +30A
Pololu item #: 1187
Price: $8.95
Quantity:

ACS714 Current Sensor Carrier -30 to +30A

This board is a simple carrier of Allegro’s ±30A ACS714 Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.1 kV RMS. This version accepts a bidirectional current input with a magnitude up to 30 A and outputs a proportional analog voltage (66 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 to 5.5 V and is intended for use in 5 V systems.
