CS5460A-BSZ集成电路（IC）的电能计量规格书PDF中文资料

CS5460A-BSZ属于集成电路（IC）的电能计量。由凌云逻辑制造生产的CS5460A-BSZ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 CS5460A is a highly integrated power measurement solution which combines two ∆Σ Analog-to-digital Converters (ADCs), high-speed power calculation functions, and a serial interface on a single chip. It is designed to accurately measure and calculate: Real (True) Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications. The CS5460A interfaces to a low-cost shunt resistor or transformer to measure current, and to a resistive divider or potential transformer to measure voltage.
