DESCRIPTION

The SAMES SA9105A Three Phase

unidirectional Power/Energy metering

integrated circuit generates a pulse rate

output, the frequency of which is proportional

to the power consumption. The SA9105A

performs the calculations of 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 SA9105A 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) packages types.
