  • The STPM33 energy metering evaluation board is a class 0.2, single-phase meter which includes tamper monitoring, CT and shunt current sensors for power line systems with Vnom= 140 to 300 V(RMS), Inom/ Imax= 5/100 A(RMS), flin= 50/60 Hz ± 10% and Tamb= -40 to +85 °C.

    Measured active/reactive power can be output from two programmable LEDs on the board.
    The board can be interfaced with a PC running evaluation software through an isolated RS232 port, or through the STEVAL-IPE023V1 USB isolated interface tool for configuration and data reading.
    The board also has SPI/UART pins available to interface a microcontroller for application development.

    Key Features

    • 0.2% accuracy single-phase meter with tamper monitoring
    • Vnom(RMS)= 140 to 300 V, Inom/Imax(RMS)= 5/100 A, flin= 50/60 Hz ± 10%
    • Tamper detection though neutral current monitoring
    • Connector for USB isolated hardware programmer tool STEVAL-IPE023V1 and PC GUI
    • RS232 and UART isolated connectors to PC GUI
    • SPI/UART switch for device peripheral selection
    • 2 programmable LEDs on board
    • Digital expansion to external system-on-chip or MCU
    • 3.3 V power supply: external or through STEVAL-IPE023V1 isolated USB board
    • IEC61000 standard compliant
    • RoHS compliant
