DESCRIPTION
The SAMES SA2005F is an enhancement of the SA9105F. A precision oscillator and the loop capacitors are integrated on chip. The SAMES SA2005F three phase bidirectional power/energy metering integrated circuit generates pulse rate outputs for positive and negative energy directions. The frequency of the pulses is proportional to the measured power consumption. The SA2005F performs active power calculation. The method of calculation takes the power factor into account. Energy consumption is determined by integrating the power measurement over time. This innovate universal three phase power/energy metering integrated circuit is ideally suited for applications such as residential and industrial energy metering and control. The SA2005F integrated circuit is available in 20 pin dual-inline plastic (DIP-20), and 20 pin small outline (SOIC-20) package types.
