Dedicated power meter IC, the sampling voltage and current signals to be processed and multiplied

Power industry development requires electrical measuring instruments with suitable technical progress, power generation, transmission, distribution and consumption of power is required for accurate measurement. Meter has been one hundred years since the birth of history, the earliest and still widely used induction meter as a traditional power meter, the energy metering work has played a significant role. It has a simple structure, good  Air circuit breaker  and inexpensive features. Full  mcb circuit breaker meter electronic energy meter by the user power supply voltage and current real-time sampling, using a dedicated power meter IC, the sampling voltage and current signals to be processed and converted into electrical energy by  Circuit breaker  a pulse output proportional display . If necessary, it can be based on the provisions of the protocol (communication protocol), the stored data (electricity, etc.) uploaded to the host computer (master), the PC can also be used on the meter, electricity sales management. Because of its induction meter unparalleled advantages, developing very rapidly in recent years. With full electronic energy meter replace induction meter, in developed countries, the average annual rate of more than 20% in the replacement.
