DTS732 TYPE THREE PHASES FOUR WIRES ELECTRONIC ACTIVE POWER METER The type DTS732 adopts three integrate circuits ADE7755 specially for energy metering. Its accuracy basically can't be affected by the temperature, high voltage, and high harmonics. After a piece of meter sold out from the factory, it did not need any adjustment thus significantly delay the inspection cycle. The meter is designed for using in household, commerce and industrial customers in single and three phases network services. It's performance conforms IEC1036,IEC62052-11, IEC62053-21 and GB/T17215?002 standards. Meanwhile, it also has infrared and 485 communication functions, communication stipulations support DL/T645?997 《Multi function Power Meter Communication Stipulations》. MAIN FEATURE: Accurately measuring of positive, negative cumulative energy consumption. The calculation type of total power can be set to absolute amount of A,B,C phases and algebraic amount of those. Adopts LCD with wide range temperature and wide visual angle displaying the data. Register the power of the current month and total last twelve months. Digits of the display pattern are six integers and two decimals (or one) Display date, time, No. of the meter, etc relative assistant information Inspection and alarm function of voltage loss and phase failure. Inspection and alarm function of reverse phase sequence connection Inspection and alarm function of non current. Inspection and alarm function of current anti-polarizing each phase Reverse display function of total power Displaying current total energy consumption when power off and also have enquiry function by button. Program the system with the function of preventing quick operation bring by fault of parts. Infrared and 485 communication function, support metering by shorten digits meter number. Average using lifetime can reach more than 10 years.
