WattNode BACnet

The WattNode BACnet is a kilowatt hour kWh energy and power meter that communicates on a EIA RS-485 network, measures 1, 2, or 3 phases with voltages from 120 to 600 volts Vac and currents from 5 to 6,000 amps in delta (phase to phase) and wye (phase to neutral) configurations.

Diagnostic LEDs

Our diagnostic LEDs provide a per-phase indication of power (green flashing) and negative power (red flashing) to help troubleshoot connection problems, like swapped CTs, or excessive line voltage. The WattNode BACnet meter also has a red/yellow/green communication LED to indicate traffic, configuration problems, bus contention and other conditions. See the manual for full descriptions.

Measurements

• True RMS 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 (Phase A, B, C, and average of all phases)
• True RMS Energy - Watthours Wh kWh (Phase A, B, C, and sum of all phases)
• Reactive Energy - VAR-hours (Phase A, B, C)
• AC Line Frequency
• RMS Voltage (Average and Phase A, B, C phase-to-phase and phase-to-neutral )
• RMS Current (Phase A, B, C)
• Demand
• Peak Demand

Features

• Small form factor for easy installation inside most electrical panels, see a sample installation diagram
• Pluggable screw terminals for easy wiring
• 0.5% accuracy nominal (see manual for details)
• True RMS power even with leading or lagging power factor and chopped or distorted waveforms
• Measure variable speed drive pumps and motors
• Uses safe CT's (current transformers), producing 0.333 Vac at rated current.
  • Split core CTs for quick installation
  • Solid core CTs are less expensive and prevent tampering
  • Bus bar CTs for high current applications (standard and custom sizes)
• UL, cUL Listed, CE Mark - Designed and tested for safety and use throughout North America and the European Union.
• Assembled in USA, qualified under the Buy American provision in the American Recovery and Reinvestment Act of 2009 (ARRA).
• Five year warranty

Safety Note

Warning: Hazardous Voltages - Only qualified personnel or licensed electricians should install the WattNode meter and current transformers.
