EVALSTPM32: Class 0.2, Single-Phase Power Meter with Shunt Current Sensor

Summary

The STPM32 energy metering evaluation board is a class 0.2, single-phase meter with shunt current sensor 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.

  • 0.2% accuracy single-phase meter reference design

  • USB port for connection to the isolated hardware programmer STEVAL-IPE023V1 and PC GUI

  • RS232 and UART isolated port for connection to PC GUI

  • SPI/UART switch for device peripheral selection

  • 2x programmable LEDs on-board

  • Digital expansion to external system-on-chip or MCU

  • Power supply 3.3 V: external or through the STEVAL-IPE023V1 isolated USB board

  • IEC61000 standard compliant
