WattNode - Three phase energy meter

The WattNode® ModBus Wattmeter is a kilowatt hour kWh energy and power meter that communicates with the ezeio controller over a RS-485 network. The WattNode® uses external Current Transformers. Select the right size CT for your application, taking into account both the max current (Amp) and the diameter of the conductor.

Up to twenty (20) wattmeters can be connected to the same ezeio Controller.

The following measurements are made available to the ezeio*:

  • True RMS Power – Watts (Phase A, B, C, all phases)

  • Reactive Power – VARs (Phase A, B, C, all phases)

  • Power Factor (Phase A, B, C, all phases)

  • True RMS Energy – Watthours WH kWh (Phase A, B, C, all phases)

  • Reactive Energy – VAR-hours (All Phases)

  • AC Frequency

  • RMS Voltage (Phase A, B, C)

  • RMS Current (Phase A, B, C)

*The ezeio limits the total number of inputs per system to 40.
