... A transformer based power supply supplies the SA2007H energy metering IC with power. The SA2007H forms the energy/power metering front-end of the module. The PM2007HPE module can easily be connected to a micro- controller via connector CON2 thereby creating a complete power meter. THE SA2007H ENERGY METER IC The SAMES SA2007H is a single phase bidirectional dual element energy metering integrated circuit ...

... PM2007HPE MODULE OVERVIEW ANALOG SECTION The analog (metering) interface described in this section is designed for measuring 230V/60A with precision better than Class 1. The most important external components for the SA2007H integrated circuit are the current sense resistors, the voltage sense resistors and the bias setting resistor. The resistors used in the metering section should be of the same type so temperature effects are minimized ...
