WNB-3Y-480-P

  • The Pulse sub-meter is a true RMS AC watt-hour transducer with pulse output (solid state relay closure) proportional to kWh consumed. The meter 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 meter combination to meet your AC power measurement requirements.
