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.
