Kickstart and explore new metering designs with MSP430

Do you need help kickstarting your design or improving your time to market? Well, we have just the solution for you! TI Designs are now a part of our strong ecosystem, providing fast prototyping and evaluation platforms to get you up and going! It includes

  • Comprehensive designs with schematics or block diagrams, BOMs, design files and test reports
  • Designs created by experts with deep system and product knowledge, spanning TI's portfolio of analog, embedded processing and connectivity solutions
  • Support for a broad range of MSP430-based applications including metering, industrial, automotive, consumer, medical and more

If you're looking for specific TI Designs, you can check out the two new ones today.

The first design is for sub-metering applications. The TIDM-SERVER-PWR-MON - Embedded Server Power Metrology.

This embedded metering (sub-meter/e-meter) design is based on the MSP430i2040 MCU. It shows how to measure the electrical parameters of the load and read the result of measurement from the UART port. The EVM associated with this TI Design, EVM430-i2040S is also available. This EVM has built-in support of measuring AC voltage, current, active power, reactive power, apparent power, frequency, power factor, voltage THD, current THD, fundamental voltage, fundamental current, fundamental power and DC voltage, DC current, DC active power. It has the ability to detect the input voltage to work as DC or AC mode. 

The second design available to download is the TIDM-3OUTSMTSTRP - Three outlet smart power strip reference.

This design implements a high-accuracy single-phase embedded metering smart power strip application using an MSP430i2040 MCU. It is built to support measuring of AC voltage, current, active power, reactive power, apparent power, frequency, and power factor with 3 sockets measured individually.

  • document contains  about voltage and current sensing circuit...what about frequency sensing?

    A: If you are referring to measuring the line frequency for utility meters, this is done using the voltage samples and the firmware.  Therefore, the voltage sensing circuitry is applicable for frequency.
