DESCRIPTION
The SAMES SA9108F Two Phase bidirectional Power/Energy metering integrated circuit generates pulse rate outputs for positive and negative energy directions, the frequency of which is proportional to the power consumption. The SA9108F performs the calculation for active power.
The method of calculation takes the power factor into account.
Energy consumption is determined by the power measurement being integrated over time.
FEATURES
■ Performs bidirectional one or two phase power and energy measurement
■ Meets the IEC 521/1036 Specification requirements for Class 1 AC Watt hour meters
■ Operates over a wide temperature range
■ Adaptable to different types of current sensors
■ Excellent long term stability
■ Easily adaptable to different signal levels
■ Precision voltage reference on-chip
■ Two pulse rate output formats available
■ Protected against ESD
