EVALSTPM3X-3PH, Poly-Phase Energy Metering Demonstration Board with current transformers based on the STPM33, STPM34 and STM8S903. 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 degree Celsius. 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
