DESCRIPTION
The SAMES SA2005P provides a single chip active energy metering solution for three phase mechanical counter-based meter designs. Th SA2005P does not require any external trim-pots or resistor ladders for meter calibration. Calibration and meter configuration information is stored on a small external EEPROM. Meter setup stored on the EEPROM includes various metering direction...
