The STPM34 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 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.
