SA9603C

SA9603C sames PRELIMINARY SA9603C SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH SERIAL INTERFACE s FEATURES s Performs bidirectional active and reactive power/energy, frequency and voltage measurement s Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters s s Adaptable to different current sensor technologies Operates over a wide temperature range Serial interface having a RS232 protocol Precision voltage reference on-chip Tri-state output to allow parallel connection of devices s s Protected against ESD s Total power consumption rating below 25mW s DESCRIPTION The SAMES SA9603C bidirectional single phase power/energy metering integrated circuit has a serial interface with a RS232 protocol, ideal for use with a µ-Controller. The SA9603C performs the calculation for active and reactive power. The SA9603C is a direct replacement for the SA9103C with additional features for the fast reading of all register values. The integrated values for active and reactive energy as well as the mains frequency and voltage information are accessable through the serial interface as 16 bit values. This universal single phase power/energy metering integrated circuit is ideally suited for energy calculations in applications such as electricity dispensing systems (ED's), residential municipal metering and factory energy metering and control. The SA9603C integrated circuit is available in both 14 and 20 pin dual-in-line plastic 7133 (DIP-14/DIP-20)...
