M5Stack® Ammeter Unit Current Meter DC-DC Isolated 16-bit ADC ±4A

Description Ammeter Unit is a current meter that can monitor the current in real time The 16 bit ADC analog to digital converter ADS1115 is used internally to communicate through I2C 0X48 In order to ensure the measurement accuracy there is a built in DC DC isolated power supply and the I2C interface is also electrically isolated through the low power isolator 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 individually calibrated when leaving the factory with inital Accurancy 0 1 FS ±1 count resolution 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 Features ±4A range16 bit ADC conversionInital Accurancy 0 1 FS ±1 countResolution 0 3mALED power indicator4A Slow blow FuseFactory calibration Cal data saved in on board EEPROM Built in I2C isolator CA IS3020SIsolated DC DCUp to 1000 VRMS isolation withstand voltageDevelopment platform Arduin UIFlow under development 2x LEiGO compatible holesPackage Included 1x Ammeter Unit1x Grove Cable 20cm Application galvanometerSpecification ResourcesParameterWithstand voltage1000VMeasuring range±4AProtocolI2CNet Weight9gGross Weight24gProduct Size65 24 8mmPackage Size67 53 12mmMeasurement Range Gain Setting Different range resolution is different the error value of the result is different
