ADE7758 Three Independent Channels Energy Metering Evaluation Board in Pakistan

This board consists of three independent energy metering channels with bidirectional energy measurement using the ADE7758 (Analog Devices) IC. The board includes an ADE7758 24-pin SOIC IC which can communicate with any microcontroller unit to get the energy measurements using SPI protocol. It can measure the energy for up to three single-phase loads or household appliances. The technical specifications of the board are:

• Three independent single-phase energy measurement channels
• The onboard 0.01-ohm shunt resistances can allow current measurements of up to 40 Amps.
• It supports standard SPI communication protocol and can be interfaced with any microcontroller.
• The energy registers can be user programmed.
• 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
