CS5460集成电路（IC）的电能计量规格书PDF中文资料

CS5460属于集成电路（IC）的电能计量。由凌云逻辑制造生产的CS5460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。

Description

The CS5460 is a highly integrated ∆ΣAnalog-to-Digital Converter (ADC) which combines two ∆ΣADCs, high speed power calculation functions, and a serial interface on a single chip. It is designed to accurately measure and calculate: Energy, Instantaneous Power, IRMS, and VRMS for single phase 2 or 3-wire power meter applications.
