DESCRIPTION
The SAMES three phase power/energy metering module, the PM9105AF provides three
pulse rate output options, the frequency of which are proportional to the active power
consumption.
Energy consumption can be 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 three phase power/energy metering circuit is
ideally suited for energy calculations in applications using a µ-controller or mechanical
counter.
The application utilises the SAMES SA9105AF, SA9105EF or SA9105FF three phase
power metering integrated circuits for power measurement.
