DESCRIPTION

The SAMES SA9102C Single Phase unidirectional Power/Energy metering integrated circuit generates a pulse rate output, the frequency of which is proportional to the power consumption. The SA9102C performs the calculation for active power.

This method of calculation takes the power factor into account.

Energy consumption is determined by the power measurement being integrated over time.
