PM9103AP

·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
· Serial interface having a RS232 Protocol

The SAMES single phase power/energy metering module, the PM9103AP, provides energy data via a RS232 compatible serial interface.

Energy consumption of PM9103AP is determined by the power measurement being integrated over time.

The method of calculation of PM9103AP takes the power factor into account.

The output of this innovative universal power/energy meter PM9103AP is ideally suited for energy calculations in applications using a -controller.

The application ofPM9103AP utilises the SAMES SA9103CP, SA9103EP or SA9603CP power metering integrated circuits for power measurement.

As a safety measure, this application shows the current sensor connected to the neutral line. In practice, the live line may be used for current sensing, PM9103AP is provided that the supply connections (MAINS) are reversed on the module.
