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
