Provides accurate measurement at a low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications.
This WattNode Delta or Wye-connection kWh Transducer works with Magnelab AC Current Transformers and a Pulse Input Adapter to provide True RMS kilowatt hours of energy used, even for loads with non-sinusoidal waveforms.
Because these sensors tie directly into the line, they should only be used by qualified personnel. This model supports a 3-phase Delta connection of 480 VAC.
