DESCRIPTION

The SAMES SA9102F and SA9102H Single Phase bidirectional Power/Energy metering integrated circuits generate pulse rate outputs for positive and negative energy directions, the frequency of which is proportional to the power consumption. These devices perform the calculation for active power.

The method of calculation takes the power factor into account.

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