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), as well as 20 pin small
outline (SOIC-20) package types.
