DESCRIPTION

The SAMES SA2002H is an enhancement of the SA9602H, as

the circuit contains the oscillator on chip.

This innovative universal single-phase power/energy metering

integrated circuit is ideally suited for energy calculations in

applications such as residential municipal metering and factory

energy metering and control.

The SAMES SA2002H single phase bi-directional

power/energy metering integrated circuit generates a pulse

rate output with a frequency proportional to the power

consumption.

The SA2002H integrated circuit is available in 8, 14 and 20 pin

dual-in-line plastic (DIP) as well as 16 and 20 pin small outline

(SOIC) package types.

The SA2002H performs a calculation for active power. The

method of calculation takes the power factor into account.

Energy consumption can be determined by the power

measurement being integrated over time.
