WattNode Logger for LonWorks

The WattNode Logger is a kilowatt hour (kWh) energy meter that communicates on a LonWorks network, and can log 24,000+ measurement records in non-volatile memory. The WattNode Logger measures 1, 2, or 3 phases with voltages from 120 to 600 volts Vac and 5 to 6,000 amps in delta (phase to phase) and wye (phase to neutral) configurations.

Measurements

  • Net Real Energy: kilowatt-hours – kWh (Phase A, B, C, sum of all phases)
  • Positive Real Energy: kilowatt-hours (sum of all phases)
  • Bidirectional Real Power: Watts (Phase A, B, C, and sum of all phases)
  • Reactive Power: VARs (Phase A, B, C, and sum of all phases)
  • Power Factor: PF (Phase A, B, C, all phases)
  • Reactive Energy: kVAR-hours (All Phases)
  • AC Frequency
  • RMS Voltage: (Phase A, B, C)
  • Computed RMS Current: (Phase A, B, C)
  • Demand
  • Peak Demand
