DESCRIPTION
The SAMES SA9103C bidirectional Single
Phase Power/Energy metering integrated
circuit has a serial interface with a RS232
protocol, ideal for use with a µ-Controller.
The SA9103C performs the calculation for
active and reactive power.
The integrated values for active and
reactive energy as well as the mains
frequency and voltage information are
accessable through the RS232-Interface
as 16 bit values.
This innovative 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 SA9103C 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.
