FEATURES
n sames Performs bidirectional power and energy measurement Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters Protected against ESD Power consumption rating typically 25mW n Adaptable to different types of current sensors Operates over a wide temperature range Precision voltage reference on-chip Two output signal formats available n n n n n n DESCRIPTION
The SAMES SA9102F and SA9102H Single Phase bidirectional Power/Energy metering integrated circuits generate pulse rate outputs for positive and negative energy directions, the frequency of which is proportional to the power consumption. These devices perform the calculation for active power. The method of calculation takes the power factor into account. Energy consumption is determined by the power measurement being integrated over time. These innovative universal power/energy metering integrated circuits are ideally suited for energy calculations in applications such as electricity dispensing systems (ED's), residential municipal metering and factory energy metering and control.
