描述 Description

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.FEATURES
?Functionally compatible with the SA9105F with reduced external components
?Performs bidirectional one, two or three 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
?Uses current transformers for current sensing
?Easily adaptable to different signal levels
?Precision voltage reference on chip
?Precision oscillator on chip.
?Protected against ESD
