DESCRIPTION

The SAMES single phase power/energy metering module, the PM9102AP, provides two pulse rate output options, the frequency of which are proportional to the active power consumption.

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

The method of calculation takes the power factor into account. The output of this innovative universal power/energy metering circuit is ideally suited for energy calculations in applications using a µ-controller or mechanical counter. The application utilises the SAMES SA9102CP, SA9102FP, SA9102HP, SA9602EP (DIP-20), SA9602HP (DIP-20) or SA9602MP power metering integrated circuits for power measurement.
