With the growing consumption of energy worldwide, particularly in the residential market, utility providers need
increasingly accurate and cost-effective energy metering solutions. The Kinetis® KM3x_256 series
single-phase electricity meter reference design addresses these accuracy and cost needs by providing a
high-performance analog front end (24- bit AFE) combined with an embedded programmable gain amplifier (PGA) to
increase the accuracy of energy measurement, along with a cost-effective shunt sensing circuit implementation and
bill of materials (BOM).
The single-phase power meter reference design is used for measurement and
registration of active and reactive energy in single-phase two-wire networks for direct connection. This power
meter reference design includes software, hardware design files (Gerbers, schematic, and layout), and
documentation. It is pre-certified according to European EN50470- 1, EN50470-3, class B and C, as well as to IEC
62053-21 and IEC 62052-11 international standards for electronic meters of active energy classes 2 and 1.
