Overview
Provides accurate measurement at a low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. This WattNode Delta or Wye-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 only be used by qualified personnel. This model supports a 3-phase Delta-connection of 480 VAC.
Features
- Measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations
- Use with wide choice of CTs (sold separately); ratings from 5 to 1500 amps
- Accurate measurement of 1-,2-, or 3-phase configurations
- Easy to install and wire
- Pulse output: 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
- Bidirectional metering: net metering for PV (photovoltaic) solar and wind power generation with only one meter
- Metering of variable frequency drives
- Line powered: no external supply required
- Detachable terminal blocks: easy to install and remove.
- UL, cUL listed: designed and tested for safety and use throughout North America
