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)

Flexible waveform buffer
Able to resample continuously waveforms to ensure 64 points per line cycle for ease of external harmonic analysis
Events, such as dip and swell, can trigger waveform storage
Advanced metrology feature set
Total and fundamental active and apparent power
Fundamental reactive power
Total and fundamental IRMS, VRMS
Power factor
Tested to support active energy standards: IEC 62053-21, IEC 62053-22, EN 50470-3, OIML R46, and ANSI C12.20 based on the ADE9039 and ADE1139
