Current sensor ACS709 (+/- 75A)

Current sensor operating in the +/- 75A range based on the Hall effect. The output is analog voltage. Power supply from 3V to 5.5V, so it can work directly with both 3.3V and 5V systems.

Usage with a Lan Controller

Lan Controller v3.0/3.5+(3.5, 3.6, 3.7, 3.8) only measures direct current with this sensor.

When used with Lan Controller v3.0, the sensor should be powered from 3.3V from the IDC10-1 connector and the INP1-4A inputs used.

When used with Lan Controller v3.5+ the sensor should be powered from 3.3V from the IDC10-1 connector and the INPA1-4 inputs used or powered from 5V and the INPA1-2 inputs used.

Before use, the indication should be calibrated in the Inputs tab on the Lan Controller page.
