Product Summary
The SA9904BSA is a three phase bi-directional energy/power metering integrated circuit that Measured values for active and reactive energy, the mains voltage and frequency for each phase are accessible through the SPI interface from 24 bit registers. The SA9904BSA active and reactive energy registers are capable of holding at least 52 seconds of accumulated energy at full load. The SA9904BSA has an integrated SPI serial interface for communication with a micro-controller. mains voltage zero crossover is available on the F50 output.
