DESCRIPTION
The SAMES SA9103E Single Phase
bidirectional Power/Energy metering
integrated circuit has a serial interface with
a RS232 protocol, ideal for use with a µ-
Controller. The SA9103E performs the
calculation for active power.
The integrated value for active energy is
accessable through the RS232-Interface
as a 16 bit value.
This innovative universal single phase
power/energy metering integrated circuit
is ideally suited for energy calculations in
applications such as electricitydispensing
systems (ED's), residential municipal
metering and factory energy metering and
control.
The SA9103E 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.
