Product overview

Description

The STPM33, STPM34 poly-phase evaluation board is a Class 0.2, single-phase or poly-phase meter with current transformer sensors for power line systems of Vnom= 140 to 300 VRMS, Inom/ Imax = 5/100 ARMS, flin = 50/60 Hz ± 10% and Tamb= -40 to +85 °C. Measured data from the STPM33 and STPM34 are read by the STM8S903 device for 3-phase energy and power calculations and the active/reactive cumulative LED signals generation.
To display all measurements, the board can be interfaced with PC running evaluation software through an isolated USB port, which provides also the 3.3 V power supply.
The board has also SPI/UART pins available to be interfaced to an external microcontroller for further application development.
