DDSF870B Single phase electronic multi-rate kilowat-hour meter module

Single phase electronic multi-rate kilowatt-hour meter is a kind of electric energy measuring meter which adopt special integrated circuit and new technology of micro-electronics with SMT technic to manufacture, it has following features: circuit design of preventing electromagnetic disturbance, widely working voltage range, good reliability,high accuracy, low power consumption, long life, high accuracy, prevent electricity theft.
    The product can accurately and directly measure 50Hz active energy consumption from single phase AC electricity net, the part of meter register adopt ADE7755 chip, through out to collect loop signal from DC and AC current, conversion from electric power value to correspond electric power pulse signal, controling chip according to the customer programme period of time, take different time period power pulse register into correspond rate, and complete the function of displaying and communication ,thus achieving hours metering functions.
