DESCRIPTION
The SAMES SA9103C bidirectional Single Phase Power/Energy metering integrated circuit has a serial interface with a RS232 protocol, ideal for use with a µ-Controller. The SA9103C performs the calculation for active and reactive power.
The integrated values for active and reactive energy as well as the mains frequency and voltage information are accessable through the RS232-Interface as 16 bit values.
FEATURES
■ Performs bidirectional active and reactive power/energy, frequency and voltage measurement
■ Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters
■ Protected against ESD
■ Total power consumption rating below 25mW
■ Adaptable to different current sensor technologies
■ Operates over a wide temperature range
■ Serial interface having a RS232 protocol
■ Precision voltage reference on-chip
■ Tri-state output to allow parallel connection of devices
