WNC-3Y-208-BN

  • The BACnet (MS/TP) sub-meter is a multi-function electric 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.

  • BACnet Communication
    • Protocol: BACnet MS/TP (RS-485)
    • Baud Rates: 9600, 19200, 38400, and 76800 baud
    • Duplex: Half (two-wire plus common)
    • Parity (default): N81 (no parity, eight data bits, one stop bit)
    • BACnet Buffer: 512 bytes (480 byte maximum APDU length)
    Electrical
