The CCS WattNode Pulse WNB-3D-240-P is a true RMS AC watt-hour transducer with pulse output proportional to kWh consumed. WattNode Pulse model WNB-3D-240-P measures 1 phase with 208Vac and 1 phase with 240Vac with no neutral configurations, 1 phase 3-wire with 120 to 240Vac, 3 phase 3-wire Delta with 208 to 240Vac with no neutral configuration, and 3 phase 4-wire Wye configuration with 120 to 208Vac.
*Delta model WNC-3D-240-P works either with or without a neutral connection, but require a line-to-line voltage connection for operating power.
