EVALSTPM32 EVAL BOARD FOR STPM32

Single-phase energy metering evaluation board with shunt current sensor based on the STPM32

Description

The STPM32 energy metering evaluation board is a class 0.2, single-phase meter with shunt current sensor for power line systems with V_nom= 140 to 300 V_(RMS), I_nom/ I_max= 5/100 A_(RMS), f_lin= 50/60 Hz ± 10% and T_amb= -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.
