Description

WattNode Modbus

The WattNode Modbus is a kilowatt hour kWh energy and power meter that communicates on a EIA RS-485 network, measures 1, 2, or 3 phases with voltages from 120 to 600 volts Vac and currents from 5 to 6,000 amps in delta (phase to phase) and wye (phase to neutral) configurations.

Diagnostic LEDs

Our diagnostic LEDs provide a per-phase indication of power (green flashing) and negative power (red flashing) to help troubleshoot connection problems, like swapped CTs, or excessive line voltage. The WattNode Modbus meter also has a red/yellow/green communication LED to indicate traffic, configuration problems, bus contention and other conditions. See the manual for full descriptions.

Measurements

  • Supports floating point and integer registers
  • True RMS Power - Watts (Phase A, B, C, and sum of all phases)
  • Reactive Power - VARs (Phase A, B, C, and sum of all phases)
  • Power Factor (Phase A, B, C, and sum of all phases)
  • True RMS Energy - Watthours WH kWh (Phase A, B, C, and sum of all phases)
  • Reactive Energy - VAR-hours (Phase A, B, C)
  • AC Line Frequency
  • RMS Voltage (Phase A, B, C)
  • RMS Current (Phase A, B, C)
  • Demand
  • Peak Demand

Features

  • Small form factor for easy installation inside most electrical panels, see a sample installation diagram
  • Pluggable screw terminals for easy wiring
  • 0.5% accuracy nominal (see manual for details)
  • True RMS power even with leading or lagging power factor and chopped or distorted waveforms
  • Measure variable speed drive pumps and motors
  • Uses safe CT's (current transformers), producing 0.333 Vac at rated current.
    • Split core CTs for quick installation
    • Solid core CTs are less expensive and prevent tampering
    • Bus bar CTs for high current applications (standard and custom sizes)
  • UL, cUL Listed - Designed and tested for safety and use throughout North America.
  • Assembled in USA, qualified under the Buy American provision in the American Recovery and Reinvestment Act of 2009 (ARRA).
  • Five year warranty

Safety Note

Warning: Hazardous Voltages - Only qualified personnel or licensed electricians should install the WattNode meter and current transformers.
