Package: DIP-20
SOIC-20
DESCRIPTION
The SAMES SA9102C Single Phase
unidirectional Power/Energy metering
integrated circuit generates a pulse rate
output, the frequency of which is
proportional to the power consumption.
The SA9102C performs the calculation for
active power.
This method of calculation takes the power
factor into account.
Energy consumption is determined by the
power measurement being integrated over
time.
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 SA9102C 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.
