EVALSTPM33

STPM33 energy metering evaluation board is a class 0.2, single phase meter which includes tamper monitoring, CT and shunt current sensors based on the STPM33 for power line systems with Vnom = 140 to 300V(RMS), Inom / Imax = 5/100A(RMS), flin = 50/60Hz ± 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.
