Description :

PM9102AP SINGLE PHASE POWER/ENERGY METERING MODULE PULSE OUTPUT FEATURES n sames SA9102 / SA9602 APPLICATION NOTE Performs both power and energy measurement Meets the accuracy requirements for Class 1 AC Watt hour meters Protected against ESD n Total power consumption rating below 500mW (excluding current sensing) Uses a shunt resistor for current sensing Operates over a wide temperature range n n n n DESCRIPTION The SAMES single phase power/energy metering module, the PM9102AP, provides two pulse rate output options, the frequency of which are proportional to the active power consumption. 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 metering circuit is ideally suited for energy calculations in applications using a µ-controller or mechanical counter. The application utilises the SAMES SA9102CP, SA9102FP, SA9102HP, SA9602EP (DIP-20), SA9602HP (DIP-20) or SA9602MP 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.

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. Voltages are specified with reference to Live. The SA9102 and SA9602 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. t = 500ms t = 1ms ELECTRICAL CHARACTERISTICS (Over the temperature range -10°C to +70°C, unless otherwise specified.
