Product Detail

CCS model RWNC-3D-240-BN is a revenue grade kilowatt hour energy and power meter that communicates on an EIA RS-485 network. WattNode Revenue BACnet model RWNC-3D-240-BN 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 RWNC-3D-240-BN works either with or without a neutral connection, but requires a line-to-line voltage connection for operating power.
