Single Phase Uni-directional Power / Energy Metering IC with Instantaneous Pulse Output
SA2002E
sames
+ FEATURES + Functionally compatible with the SA9602E with reduced
external components
+ Uni-directional power and energy measurement + Meets the IEC 521/1036 Specification requirements for
Class 1 AC Watt hour meters
+ Protected against ESD
DESCRIPTION
The SAMES SA2002E is an enhancement of the SA9602E, as the circuit contains the oscillator on chip.
The SAMES SA2002E single phase uni-directional power/energy metering integrated circuit generates a pulse rate output with a frequency proportional to the power consumption.
The SA2002E performs a calculation for active power. The method of calculation takes the power factor into account. Energy consumption can be determined by the power measurement being integrated over time.
+ Total power consumption rating below 25mW + Adaptable to different types of current sensors + Operates over a wide temperature range + Precision voltage refere.
