  • Products introduction: The PDJ-230 series of three-phase network electric power meter is mainly used in real-time monitoring and controlling of normal electrical equipment in 400V power distribution system, and it can be cooperated using with transformer, voltage divider and current divider etc, to realize the comprehensive management function of three-phase voltage and current. It’s also equipped with switching value input & output ability, and combined with measurement, calculation, control and communication these four functions. It’s the ideal terminal to realize distribution automation system.

    The PDJ-230 series of three-phase network electric power meter has combined with complete measurement, calculation and control output functions inside, with built-in effective values measuring processor, it’s specially suits for serious polluted occasions by higher harmonic. With abundant I/O interfaces, it can flexibly expand and satisfy different customers’ needs.
     
    Application field: Building energy consumption monitoring system, electric energy management system, energy management information system, industrial automation, electric energy calculating BS, substation automation, power distribution network automation, intelligent distributor, intelligent constructions and large-scare UPS system.
