Energy Metering Chipset for Polyphase Meters with di/dt Current Sensors

* Complete polyphase direct connect meter or split-phase meter using a PCB-based di/dt current sensor, and ADE9039 and ADE1139 chipset

* Strong immunity to AC magnetic tampering

* Immune to DC magnetic fields

* Ideal for AC applications from 32 A to 1 kA

* Supports Class 0.2 accuracy

* System uses a small amount of low cost PCB area

* Channel crosstalk is typically less than 0.1%

* Resilience to fast high-current waveforms

* Less than 3 mA AC offset is achievable due to sensor immunity to electrostatic coupling

* Computes active energy, reactive energy, and apparent energy on each phase and on the overall system

* Less than 0.1 % error in active energy over a dynamic range of 2000 to 1 at TA = 25 °C

* Less than 0.1 % error in voltage RMS over a dynamic range of 1000 to 1 at TA = 25 °C

* Less than 0.1 % error in current RMS over a dynamic range of 1000 to 1 at TA = 25 °C

* Single positive 3.3 V supply

* Power quality measurements

* VRMS½, IRMS½ refreshed each half cycle

* Dip and swell monitors

* Line frequency—one per phase

* Zero crossing with a timeout availability

* Phase angle measurements

* Total harmonic distortion (THD)
