Reinforced isolation up to 517 VRMS in a single package eliminates the need for dual isolated supplies
Active, reactive, and apparent power measurements, and power factor
RMS and instantaneous voltage and current measurements
0.85 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
Dedicated voltage zero crossing pin
Overcurrent fault output pin
Hall-effect-based current measurement with common mode stray field rejection
User-programmable VRMS under/overvoltage pin
1 kHz bandwidth
Current-sensing range from 0 to 90 A
I²C or SPI communication
User-programmable through EEPROM registers
16-bit voltage and current ADCs
