EVALSTPM34 Dual-phase energy metering evaluation board with 2 current transformers based on the STPM34

The EVALSTPM34 evaluation board is a class 0.2, dual-phase meter with 2 CTs 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 USB-to-UART port, or through the STEVAL-IPE023V1 USB (SPI) isolated interface tool for configuration and data reading.

The board also has SPI/UART pins available to interface a microcontroller for application development.
