Buck resulting small voltage signal from the collection and measurement of electrical energy measurement IC

Single-phase electronic watt-hour meter Principle and characteristics of single-phase electronic watt-hour meter is a measure of the core part of the chip, with some peripheral devices to achieve energy  circuit breakers . Current sampling using shunt resistors; voltage circuit RC Buck fixed network; two loop current sampling, the resulting small voltage step-down signal from the collection and measurement of  mcb circuit breaker  energy measurement IC, the output electrical pulse is used to verify the accuracy and to  power transformers such as automatic meter reading and driving the expansion of energy value display of degrees. Single-phase electronic watt-hour meter main features: error stability, good linearity, which is incomparable advantage of mechanical watches.
