Description :

PM9103AP SINGLE PHASE POWER/ENERGY METERING MODULE SERIAL INTERFACE FEATURES n sames SA9103 / SA9603C APPLICATION NOTE 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) n Uses a shunt resistor for current sensing Operates over a wide temperature range Serial interface having a RS232 Protocol n n n n n DESCRIPTION The SAMES single phase power/energy metering module, the PM9103AP, provides energy data via a RS232 compatible serial 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 µ-controller. The application 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, provided that the supply connections (MAINS) are reversed on the module. 1/10 4309 PDS038-SA9103-001 REV.C 11-08-98 PM9103AP BLOCK DIAGRAM IN OUT SHUNT SA9103 SA9603 OPTO COUPLER D-sub CONNECTOR NEUTRAL NEUTRAL NEUTRAL LIVE POWER SUPPLY VOLTAGE SENSE POWER METER DR-01448 OPTO COUPLER ABSOLUTE MAXIMUM RATINGS- Parameter Symbol Supply Voltage (Note 1) VAC Current Sense Input (Note 1) VIV Storage Temperature TSTG Operating Temperature TO Max Current IMAX through Sensor IMAX Min -2.5 -25 -10 Max 540 +2.5 +125 +70 (Note 2) 800 (Note 3) 2000 (Note 4) Unit V V °C °C A A Note 1: Voltages are specified with reference to Live. Note 2: The SA9103 and SA9603C integrated circuits are specified to operate over the temperature range -10°C to +70°C. The module functionality will however depend upon the external components used. Note 3: t = 500ms Note 4: t = 1ms *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 operational sections of this specification, is not implied. Exposure to Absolute Maximum Ratings for extended periods may affect device reliability. 2/10 sames PM9103AP ELECTRICAL CHARACTERISTICS (Over the temperature range -10°C to +70°C, unless otherwise specified.
