DESCRIPTION
The SAMES SA9105F Three Phase
bidirectional 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 SA9105F 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.
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 SA9105F 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.
