From Accessories
AC Power Measurement, True Power, kWh Reactive Power, VARs, Power Factor, Individual Phase Measurements. The Watt Meter is a kilowatt hour (kWh) energy and power meter that communicates to Volucalc Hybrid on a EIA RS-485 network. It 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.
