SA9105 APPLICATION NOTE
PM9105AF
THREE PHASE POWER/ENERGY METERING MODULE
PULSE OUTPUT
FEATURES
n Performs one, two or three phase power n Uses current transformers for current
and energy measurement
sensing
n Meets the accuracy requirements for n Three pulse rate outputs available
Class 1 AC Watt hour meters
n Protected agianst ESD
n Operates over a wide Temperature
Range
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.

Note 2:
The SA9105 integrated circuit is specified to operate over the temperature
range -10°C to +70°C. The module functionality will however depend upon
the external components used.
* Stresses above those listed under "Absolute Maximum Ratings" may cause permanent
damage to the device. This is a stress rating only. Functional operation of the device
at these or any other conditions above those indicated in the operation sections of this
specification, is not implied. Exposure to Absolute Maximum Ratings for extended
periods may affect device reliability.
