The HOBO WNB-3D WattNode Series Transducer Sensors provide accurate measurements at low cost 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.
