WattNode® Wide-Range Meter for Modbus

  • The new WND-WR-MB provides over fifty electrical measurements over a Modbus RTU RS-485 network
  • Designed as a universal line-powered meter, it works on any utility service from 100 to 600 Vac, single or three-phase, wye, or delta
  • The WND-WR-MB has the same dimensions as its WattNode Modbus predecessor but its expanded register map provides many unique features not previously offered in the submetering market
  • New registers include fast power for export limiting, registers to correct wiring errors remotely, potential transformer ratio for 4160 Vac and higher utility services, and SunSpec compliance
  • Standard Features
    • Measures 100 to 600 Vac single-phase or three-phase, wye or delta
    • Line powered from 100 to 600 Vac, line-neutral or line-line
    • Correct wiring errors remotely
      • Change a CT's polarity
      • Change a CT to a different line voltage
    • PT ratio register for use with potential transformers
