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

Sale priceR 5,839.17

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.
