The SAMES SA2002H single phase bi-directional power/energy metering integrated cicuit generates a pulse rate output with a frequency proportional to the power consumption. 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. 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 eneryg metering and control. The SA2002H integrated circuit is available in 8 pin dual-in-line plastic (DIP) as well as 16 and 20 pin small outline (SOIC) RoHS compliant package types.
