DESCRIPTION
The SAMES SA9105E Three Phase
unidirectional Power/Energy metering
integrated circuit generates a pulse rate
output, the frequency of which is proportional
to the power consumption. The SA9105E
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 three
phase power/energy metering integrated
circuit, is ideally suited for applications such
as residential and industrial energy metering
and control.
The SA9105E integrated circuit is available
in 40 pin dual-in-line plastic (DIP-40), as
well as in 44 pin plastic leaded chip carrier
(PLCC-44) package types.
