STEVAL-IPE008V1

Energy meter (3-phase) demonstration board

based on the STPM01 and STR715FR0

Features

monitored using a single-phase device

VIPer12ADIP-E

Description

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

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 single-

phase energy meter applications or as a

peripheral in a microprocessor based single- or 3-

phase 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.
