DESCRIPTION

The SAMES SA9604A Bidirectional Three Phase Power/Energy metering integrated circuit has a serial interface, ideal for use with a µ-Controller. The SA9604A performs the calculation for active and reactive power or energy, mains voltage sense and frequency.

The measurements performed and the resultant register values are provided for individual phases.

The integrated values for active and reactive energy, as well as the mains voltage sense and frequency information, are accessable through the SPI as 24 bit values.

This innovative universal three phase power/energy metering integrated circuit is ideally suited for energy calculations in applications such as primary industrial metering and factory energy metering and control.

The SA9604A integrated circuit is available in both 20 pin dual-in-line plastic (DIP-20), as well as 20 pin small outline (SOIC-20) package types.
