WattNode 208-240VAC 2 or 3 Branch Circuit kWh Transducer Sensor - T-WNB-3Y-208-P


WattNode 208-240VAC 2 or 3 Branch Circuit kWh Transducer Sensor - T-WNB-3Y-208-P
magnifier icon

The WattNode sensor provides accurate kWh measurement at a low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications.

This WattNode kWh Transducer works with Magnelab AC Current Transformers and a Pulse Input Adapter, or a HOBO® Data Node pulse input port 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 be used only by qualified personnel. This model supports up to 3 separate 120 VAC single-phase branch circuits or individual 120 VAC phases of a 3-phase wye-connection 208/240 VAC circuit.

  • Measures up to 3 separate branch circuits simultaneously, reducing complexity and cost.
  • Use with wide choice of current transformers (sold separately) - ratings from 5 to 1500 amps.
  • Accurate measurement of multiple single phase or each phase of 3-phase configurations.
  • Easy to install and wire.
  • Individual pulse outputs for each circuit - compatible with pulse input logger models.
  • Small size - can be installed in existing service panels or junction boxes.
  • Diagnostic LEDs - confirms proper installation for all phases.
  • Line powered - no external supply required.
  • Detachable terminal blocks - easy to install and remove.
