STEVAL-IPE008V1

STEVAL-IPE008V1 Energy meter (3-phase) demonstration board based on the STPM01 and STR715FR0 Data Brief Features ■ 3-phase meters ■ Multi-chip topology, in which each phase is monitored using a single-phase device ■ Common clock network ■ Power supply in fly-back topology using a VIPer12ADIP-E ) s ( ct u d o r P e Description STEVAL-IPE008v1 The STEVAL-IPE008V1 demonstration board shows how to design a 3-phase meter using STPM01 as measuring device and a VIPer12ADIP-E as SMPS (switch mode power supply). The STPM01 is a metering ASSP implemented in an advanced 0.35 µm BCD6 technology. It is designed for the effective measurement of active, reactive, apparent energies, VRMS, IRMS, instantaneous voltage and current, and frequency in power line systems that use the current transformer, Rogowski coil and/or shunt principle. This device can be used as a standalone on-board metering device in singlephase energy meter applications or as a peripheral in a microprocessor based single- or 3phase meter. In a standalone configuration STPM01 outputs a pulse train signal having a frequency proportional to the active power used, while in peripheral mode STPM01 is used in a microprocessor based application. In this case, measured data are read at a fixed interval from the device internal registers by means of SPI interface processed by a microcontroller. ) (s AM03203v1 t e l o s b O t c u d o r P e t e l o s b O November 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/8 www.st.com 8 Circuit schematics 1 STEVAL-IPE008V1 Circuit schematics Figure 1.
