WattNode Branch Circuit kWh Transducer Sensor

Sale priceR 9,142.22
SKU: T-WNB-3Y-208-P



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 only be used 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.

Highlighted Features

  • Measures up to 3 separate branch circuits simultaneously, reducing complexity and cost
  • Use with a wide choice of current transformers (sold separately); ratings from 5 to 1500 amps
  • Accurate measurement of multiple single phases 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
