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.
