EVALSTPM33 Single-phase with tamper monitoring energy metering demonstration board with CT and shunt based on the STPM33

STMicroelectronics

The EVALSTPM33 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 USB-to-UART 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.
