DESCRIPTION
PIN CONNECTIONS
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.
