ADE7758 3-Phase Bidirectional Energy Metering Evaluation/Development Board in Pakistan

This development board is made for three-phase bi-directional energy metering purposes using the ADE7758 (Analog Devices) IC. The board includes ADE7758 24 pin SOIC IC which can communicate with any microcontroller unit to get the energy measurements. It can be used to measure the energy for any three-phase household appliance. The technical specifications of the ADE7758 are:

• Highly accurate; supports IEC 60687, IEC 61036, IEC 61268, IEC 62053-21, IEC 62053-22, and IEC 62053-23
• Compatible with 3-phase/3-wire, 3-phase/4-wire, and other 3-phase services
• Less than 0.1% active energy error over a dynamic range of 1000 to 1 at 25°C
• Supplies active/reactive/apparent energy, voltage RMS, current RMS, and sampled waveform data
• Two pulse outputs, one for active power and the other selectable between reactive and apparent power with programmable frequency
• Digital power, phase, and RMS offset calibration
• On-chip, user-programmable thresholds for line voltage SAG and overvoltage detections
• An on-chip, digital integrator enables direct interface-to-current sensors with di/dt output
• A PGA in the current channel allows a direct interface to current transformers
• An SPI®-compatible serial interface with IRQ
