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.
