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.
