DESCRIPTION
PIN CONNECTIONS
The SAMES SA9605A is an enhancement
of the SA9105E and SA9105F, as no external
capacitors are needed for the A/D converters.
The SAMES SA9605A Three Phase Power/
Energy metering integrated circuit generates
a pulse rate output, the frequency of which
is proportional to the absolute power con-
sumption. The SA9605A 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.
