Detailed Product Description

        DTSD238/DSSD238 three phase electrical multifunctional watt-hour meter(kwh meter,energy meter,power meter) is a kind of electric energy measuring meter which adopt a large scale of integrated circuits and use number sampling disposal technique and SMT craftwork, and designed and manufactured with nineties international advanced lever as per industrial user factual electric power consumption status. The meter can accurately measure three phase positive direction and reversed direction active energy and reactive energy electric energy, active energy and reactive energy power, voltage and current and frequency parameters etc. It can do data processing as per relevant tariff and demand. The meter can set four kinds of tariffs, four time zones and ten daily period of times.
        It posses RS485 communication interface and long-distance pulse output function. Its technical performance are completely conform to the stipulated requirements of DL/T614-1997Multifunctional Watt-hour Meterand DL/T645-1997Multifunctional Watt-hour Meter Communication Stipulationsand National electric power department standard.
The meter is used for industry user and electric power line measuring and test frequency 50Hz or 60Hz three phase AC active energy or reactive energy electric energy parameters, it is a kind of preferred product for electric energy measuring, inspection and management of distribution electricity station and transformer substation etc.
Main Characteristics
1. High accuracy, high overload, high reliability, low power consumption, small volume, light in weight and good structural performance.
2. The internationally advanced integration circuits specially used for Watt-hour Meter, permanent information keeping non-volatile storage and other hardware and software measurements are employed to prevent the meter from losing data at times when both AC power supply and internal support battery lost voltage.
3. LCD display, clear and bright.
