Low-Cost
kWh Transducer / Submeter
Multi-Color Diagnostic LEDs
Bidirectional Outputs
Perfect for Net Metering

The WattNode Pulse is a true RMS AC watt-hour transducer with pulse output (solid state relay closure) proportional to kWh consumed. The WattNode provides accurate measurement at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. The complete Pulse Output family measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations. With voltage ratings from 120 to 600 Vac and current transformer (CT) ratings from 5 to 6000 amps, there is a WattNode combination to meet your AC power measurement requirements.

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. See the manual for a full description.
Advanced Output Capabilities are available as factory options:
Standard output provides pulses on one terminal for positive energy and on another terminal for negative energy. This is useful with solar panels, where energy taken from the grid and energy fed to the grid can be metered separately with one meter (net metering).
