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.

• 0.5% nominal accuracy
• True RMS power even with leading or lagging power factor and chopped or distorted waveforms
• Measure variable speed drive pumps and motors
• Uses safe split core CT’s (current transformers) for quick installation
• UL, cUL Listed
