Product Description
Onset kWh Xducer 208/240VAC Delta (Pulse out) - T-WNB-3D-240
OverviewThe 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.
