CS5464-IS集成电路（IC）的电能计量规格书PDF中文资料

CS5464-IS属于集成电路（IC）的电能计量。由凌云逻辑制造生产的CS5464-IS电能计量能量计量集成电路可用于单相、双相和三相电力线系统中的高精度电能测量。这些器件可以测量线路电压和电流，并且可以计算有功、无功和视在电能，以及瞬时均方根电压和电流。

描述 Description

The CS5464 is an integrated power measurement device which combines three ∆Σ analog-to-digital converters, power calculation engine, energy-to-frequency converter, and a serial interface on a single chip. It is designed to accurately measure instantaneous current and voltage and calculate VRMS, IRMS, instantaneous power, active power, apparent power, and reactive power for high-performance power measurement applications.
