The design implements a highly accurate single-phase electric meter system using the MSP430AFE253 analog front end. It meets the requirements for ANSI C12.20 and IEC-62053 Class 0.2 meters. The System on Module (SoM) is designed to be a plug-in card to a larger motherboard through a standard connector. The SoM is compatible with the TI Smart Meter Board 3.0. The MSP430AFE2xx SoM is suitable for developers of smart e-meters and Distribution Automation equipment that require highly accurate energy measurement.
Single-phase electricity measurement which exceeds Class 0.2 accuracy requirements from ANSI and IEC Compatible with a variety of input circuits and sensing technologies (Shunts, Current Transformers, etc.) All analog and digital IOs available on convenient header Integrated LEDs for metrology pulse information and status notification TI Energy Library firmware calculates all energy measurement parameters including active and reactive power and energy, RMS current and voltage, power factor, and line frequency.
