Product Details

The AD-PQMON-SL provides a complete software and hardware platform for prototyping and evaluating high performance class S polyphase energy quality monitors. The design incorporates the ADE9430 high performance, polyphase energy monitoring IC that has an advanced metrology feature set (total and fundamental active power, volt amperes reactive (VAR), volt amperes (VA), watthour, VAR hour, VA hour, total and fundamental IRMS and VRMS, power factor) and the MAX32650 ultralow power ARM cortex-M4 with FPU-based microcontroller with 3 MB flash and 1 MB SRAM. The ADE9430 enables accurate energy monitoring over a wide dynamic range through its superior analog performance and digital signal processing (DSP) core. The ADE9430 simplifies the implementation and certification of energy and power quality monitoring systems by providing tight integration of acquisition and calculation engines. This solution can be used on a 3-phase system or up to three single-phase systems.

The design also features the MAX32650, which is a part of a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT) named DARWIN. These MCUs are smart, with the biggest memories in their class and a massively scalable memory architecture. The MCU exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with 512 Mb RAM and 64 Mb flash external memories to provide flexibility. The system's firmware is based on ADI's open-source no-OS framework and ADI proprietary ADSW-PQ-CLS library.

The solution has an on-board ADuM6424A Quad-Channel Isolator with Integrated DC-to-DC Converter. This DC-DC converter is used to supply all the components on the high voltage side. The ADUM6424A and the ADUM4152, which is a 5 kV, 7-Channel, SPIsolator™ Digital Isolator for SPI (with 1/2 Aux channel directionality), are used to isolate the connection between the ADE9430 and MAX32650.

The board can be supplied from the AC input through an isolated AC/DC converter or from the USB through the LTC3306, a 1.75 A Synchronous Step-Down Regulator. A logic based on several MAX40203, an Ultra-Tiny nanoPower, 1 A Ideal Diodes with Ultra-Low-Voltage Drop, selects based on availability the supply input with priority to the AC input.

The other 1.1 V and 1.8 V voltage rails needed by the MCU are converted from the 3.3 V input by the ADP225, a Dual, 300 mA Adjustable Output, Quick Output Discharge, Low Noise, High PSRR Voltage Regulator.

For high accuracy time keeping, the MAX31343 ±5 ppm, I2C Real-Time Clock with Integrated MEMS Oscillator is used.

The add-on board includes a standalone interface (a 64 x 4 display, 2 LEDs, and 5 buttons), an SD card for long time data logging, several industrial connectivity ports, and exposes an I/O prototyping area for I2C, SPI, GPIO, UART, 3V3, GND. The prototyping area can be also used for GPS / GNSS (e.g., Accurate Synchrophasor Measurement) or for external control signals.

For industrial connectivity, these are the following possibilities:

  • T1L through the ADIN1110, an ultralow power, single port, 10BASE-T1L transceiver design for industrial Ethernet applications
  • RS-485 implemented using the ADM2587E, a 2.5 kV Signal and Power Isolated, ±15 kV ESD Protected, Full/Half Duplex RS-485 Transceiver (500 kbps)
  • Ethernet

APPLICATIONS

  • Energy and power monitoring
  • Standards compliant power quality monitoring
  • Protective devices
  • Smart power distribution units
  • Polyphase energy meters
  • Intelligent buildings
