Analog Devices Inc.США

This feature set describes a highly accurate polyphase energy measurement solution based on the ADE9039 and ADE1139 chipset with full metrology offering and using PCB- di/dt current sensing. It supports both direct-connect and split-phase meter designs, offering strong immunity to magnetic tampering and external interference while maintaining Class 0.2 accuracy over a wide current range. The system delivers precise measurement of active, reactive, and apparent energy, along with comprehensive power quality monitoring (such as RMS values, THD, and phase measurements), waveform samples for advanced waveform analysis, and event detection. Its compact, low-cost implementation, high dynamic range accuracy, and compliance with major international metering standards make it well suited for many applications, including Advanced Metering (AMI), Data center Power Distribution Units (PDU), Sub-Meters, Smart Circuit Breakers, Home Energy Management devices, etc.
