该器件针对均衡的传输线路而设计,符合ANSI TIA/EIA-485-A-98和ISO 8482:1987(E)标准。

它采用ADI公司的iCoupler®技术,在单个封装内集成了一个三通道隔离器、一个三态差分线路驱动器、一个差分输入接收器和一个isoPower DC/DC转换器。该器件采用5V或3.3V单电源供电,从而实现了完全集成的信号和电源隔离RS-485解决方案。

ADM2582E/ADM2587E驱动器带有一个高电平有效使能电路,并且还提供一个高电平接收机有效禁用电路,可使接收机输出进入高阻抗状态。

该器件具备限流和热关断特性,能够防止输出短路,并防止出现由于总线争用而引起功耗过大的情况。它采用20引脚宽体SOIC封装,其额定工作温度范围为工业温度范围。

ADM2582E/ADM2587E集成了isoPower技术,该技术采用高频开关元件通过其变压器传输电力。在PCB布局时必须特别注意满足辐射标准。欲了解电路板布局的注意事项,请参考应用笔记AN-0971:isoPower器件的辐射控制。

Power Quality Monitor Development Platform

Power Quality Monitor Development Platform

特性和优点

  • Allows prototyping of high performance, polyphase energy meters
  • Modular hardware design:
    • Metering & compute base board
    • Add-on board for COMMS and HMI
  • The base board offers flexibility in input/output (I/O) interfacing through custom add-on boards
  • Industrial connectivity: 10BASE-T1L (ADIN1110), RS-485 (ADM2587E), Ethernet (WIZ82)
  • Long time data logging (SD card)
  • Standalone interface (display, LEDs, buttons)
  • I/O prototyping area (external control signals, GPS / GNSS)
  • Publicly available software for evaluation and prototyping
  • Embedded processing implementing the complete IEC 61000-4-30 class S power quality standard (using ADI proprietary ADSW-PQ-CLS library)
  • Open-source GUI (Scopy – Cross-platform Qt application)
  • Fully isolated design for safe operation
  • Industry standard form factor compatible with DIN rail mounts

产品详情

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
