DESCRIPTION
The SAMES single phase power/energy metering module, the PM9603AP, provides energy data via a isolated SPI interface.
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 meter is ideally suited for energy calculations in applications using a micro-controller.
The application utilises the SAMES SA9603B power metering integrated circuit for power measurement.

FEATURES
■ Performs both power and energy measurement
■ Meets the accuracy requirements for Class 1 AC Watt hour meters
■ Protected against ESD
■ Total power consumption rating below 500mW (excluding current sensing)
■ Uses a shunt resistor for current sensing
■ Operates over a wide temperature range
■ Isolated SPI interface.
