DESCRIPTION
The SAMES SA9108F Two Phase bidirec-
tional Power/Energy metering integrated
circuit generates pulse rate outputs for
positive and negative energy directions,
the frequency of which is proportional to the
power consumption. The SA9108F
performs the calculation for active power.
The method of calculation takes the power
factor into account.
Energy consumption is determined by the
power measurement being integrated over
time.
The output of this innovative universal two
phase power/energy metering integrated
circuit is ideally suited for applications such
as residential and industrial energy metering
and control.
The SA9108F integrated circuit is available
in 40 pin dual-in-line plastic (DIP-40), as
well as 44 pin plastic leaded chip carrier
(PLCC-44) package types.
