SA2002E

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...
