DESCRIPTION
The SAMES SA2002E is an enhancement of the SA9602E, as the circuit contains the oscillator on chip. The SAMES SA2002E single phase uni-directional power/energy metering integrated circuit generates a pulse rate output with a frequency proportional to the power consumption. The SA2002E 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.

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 SA2002E 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.
