WattNode 208/240 VAC 3-phase Delta/Wye kWh Transducer

The WattNode provides accurate measurement at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. This WattNode Delta-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 be used only by qualified personnel. This model supports a 3-phase Delta-connection of 208/240 VAC.

The T-WNB-3D-240 Sensor is for use in Indoorenvironments

The T-WNB-3D-240 Sensor supports the following measurements:
