DESCRIPTION

The SAMES monochip three phase bidirectional kilowatt hour metering module, the

PM9110BF, provides all the required metering functions including energy measure-

ment, a 7 digit LCD driver, a tariff selection facility, an optical port as well as a pulse

output for calibration purposes.

Energy consumption is determined by the power measurement being integrated over

time.

This method of calculation takes the power factor into account.

This application utilises the SAMES SA9110AFA monochip three phase bidirectional

kilowatt hour metering IC for energy measurement.
