Ameter Unit
SKU:U086
Description
Ameter Unit is a current meter that can monitor the current in real time. The 16-bit ADS1115 ADC (analog-to-digital) converter can be used to communicate through I2C protocol (By default the I2C address is 0X48 unless manually modified).
In order to ensure the measurement accuracy, there is a built-in DC-DC isolated power supply.
The I2C interface is also electrically isolated through the low-power isolator module CA-IS3020S, This prevents noise and surges on the data bus or other circuits from entering the local ground terminal to interfere or damage sensitive circuits.
Each Unit is factory calibrated with initial accuracy of 0.1%FS, ±1 count and resolution of 0.3mA.
The unit has a maximum measurement current of ±4A, and an internal integrated 4A fuse to prevent excessive measurement current from burning out the circuit.
