DESCRIPTION

The power consumption on both the live and neutral are

continuously measured and the larger of the two is selected for

energymetering.

The SAMES SA2007M is a single-phase bidirectional energy

metering integrated circuit. It provides a mono-chip solution for

energy meters with electro-mechanical displays, such as

stepper motors and impulse counters. A precision oscillator,

thatreplacesanexternalcrystalisintegratedonchip.

The SA2007M drives the calibration LED, the indicator LEDs

andtheelectro-mechanical counterdirectly.

Two current sensor inputs allow the measurement of energy

consumptiononboththeliveandneutral.

The SA2007M integrated circuit is available in 20 pin dual-in-

line plastic (DIP-20) and small outline (SOIC-20) package

types.

Direction detection of energy flow as well as other common

tamperconditionsareflagged.
