FEATURES
n sames Performs bidirectional one, two or three phase power and energy measurement Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters Operates over a wide temperature range Uses current transformers for current sensing n n Excellent long term stability Easily adaptable to different signal levels Precision voltage reference on-chip Two pulse output formats available Protected against ESD n n n n n n DESCRIPTION
The SAMES SA9105F Three Phase bidirectional Power/Energy metering integrated circuit generates pulse rate outputs for positive and negative energy directions, the frequency of which is proportional to the power consumption. Energy consumption is determined by the power measurement being integrated over time. The SA9105F integrated circuit is available in 40 pin dual-in-line plastic (DIP-40), as well as in 44 pin plastic leaded chip carrier (PLCC-44) package types.
