ASIC 9605 For Three Phase Kwh Meter

Description:The OSE9605 is a perfect equivalent of SA9605A and an enhancement of the SA9105EAnd SA9105F, as no external capacitors are needed for the A/D converters.The OSE9605 Three Phase Power/Energy metering integrated circuit generates a pulseRate output, the frequency of which is proportional to the absolute power consumption.The OSE9605 performs the calculation for active power. The method of calculationTakes the power factor into account. Energy consumption is determined by the powerMeasurement being integrated over time.The output of this innovative universal three phase power/energy metering integratedCircuit, is ideally suited for applications such as residential and industrialEnergy metering and control.The OSE9605 integrated circuit is available in both 20-pin dual-in-line plastic(DIP-20)as well as 20-pin plastic small outline(SOIC-20)package types.Features:Functionally similar to the SA9105E and SA9105F, with reduced number of externalComponentsOutput frequency represents the absolute sum of energy on all three phasesPerforms one, two or three phase power and energy measurementMeets the IEC 61036 Specification requirements for Class 1 AC Watt hour metersOperates over a wide temperature rangeCurrent transformers for sensingExcellent long term stabilityEasily adaptable to different signal levelsPrecision voltage reference on-chipPin selectable pulse ratesSupports tamper detection
