Application

DDSF1531 series single-phase electronic multi-tariff watt-hour meteris for measuring active energy of sing lephase 22DV and 50Hz. it adopts the latest MPU tech-nology and digita lenergy measurement chip of high accuracy and wide range, it has many features such as high accuracy. wide range. high stability. low power con sumption and graceful appearance. Because LCD or LED and milit ary components are used, it is characterized with long service life. free maintenance and convenient meter reading . It can measure positively and negatiovely . and has ability of anti-elect ricity theft and output pulse, to take convenience for detecting . It is the first selection product for implementing national time­sharing electricity price policy
