Product Summary

The CS5464-ISZ is a watt-hour meter on a chip. The CS5464-ISZ measures line voltage and current and calculates active, reactive, apparent power, energy, power factor, and RMS voltage and current. There are two separate inputs to measure line, ground, and/or neutral current enabling the meter to detect tampering and to continue operating. An internal RMS voltage reference can be used if voltage measurement is disabled by tampering.
