ADE7978ACPZ - Isolated Energy Metering Chipset for Polyphase Shunt Meters

Part Number: ADE7978ACPZ

Package: LFCSP-28

Type: Energy Metering IC

Description: 3-Phase Metrology IC for Polyphase Shunt Meters

Product Overviews

ADE7978ACPZ is a high accuracy, 3-phase electrical energy measurement IC with serial interfaces and three flexible pulse outputs. The ADE7978 incorporates all the signal processing required to perform total (fundamental and harmonic) active, reactive, and apparent energy measurement and rms calculations, as well as fundamental-only active and reactive energy measurement and rms calculations. A fixed function digital signal processor (DSP) executes this signal processing.

Product Features

Enables shunt current sensors in polyphase energy meters

Immune to magnetic tampering

Compatible with 3-phase, 3- or 4-wire (delta or wye) meters and other 3-phase services

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

Power quality measurements including total harmonic distortion (THD)

Single 3.3 V supply

Operating temperature: −40°C to +85°C

Flexible I2C, SPI, and HSDC serial interfaces

Applications

Shunt-based polyphase meters

Power quality monitoring

Solar inverters

Process monitoring

Protective devices

Isolated sensor interfaces

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
