WattNode Plus for LonWorks
CCS cta linecard.png
The WattNode Plus is a kilowatt-hour (kWh) energy and power meter that communicates on a LonWorks network and measures 1, 2, or 3 phases with voltages from 120 to 600 Vac and currents from 5 to 6,000 amps in delta (line-to-line) and wye (line-to-neutral) configurations. For built-in data logging, see the WattNode Logger for LonWorks.
