   产品概述 返回TOPqWr嘉泰姆

The CXEP2347 is a low-power, single-phase energy measurement system-on-chip (SoC), and the CXEP2348 is a low-power polyphase energy measurement SoC. Based on an ARM Cortex-M3 core, the devices can run modern operating systems that monitor and report energy usage and implement communications stacks. In addition to the main administrative core, the devices include a  CPU core to perform metering functions and a discrete compute engine for the DSP related tasks necessary for accurate energy monitoring and measurement, last cycle analysis, and FFT functions to compute the frequency spectra of the selected channel. The DSP core provides the following energy and power measurement features in registers: 

● Active energy and power per phase and sum 

● Apparent energy and power per phase and sum 

● Reactive energy and power per phase and sum 

● Line voltage and current RMS 

● Neutral current RMS 

● Current vector sum, three-phase plus neutral 

● Line frequency 

● Fundamental frequency 

● Total harmonics of active power, reactive power, voltage, and currents 

● Security features
