Product brief information 

 

   Three-phase electronic multi-function electricity power meter adopts the advanced LSI, digital processing technique and SMT techniques, this product is designed and manufactured according to the international advanced new generation of electronic multi-function energy meter. The product can accurately measure forward and reverse active and reactive electric energy, active and reactive powers, parameters of voltage, current and frequency, It can provide data processing for the customers` relevant tariff and demand, It has 4 tariffs, 4 time intervals, 10 date segments, clock and 10-year calendar, infrared remote programmable meter reading, RS 485 communication interface and etc. functions. The specifications can meet the requirement of IEC62053-22:2003, IEC62053-23:2003 and IEC62056-21.

 

 Technical characteristics

 

    1. Time-of-use metering for forward and backward active energies.

    2. Time-of-use metering for 4 quadrants reactive energies.

    3. Time-of-use metering maximum electricity demands for forward and backward active energies.

    4. 4 tariffs, 4 time intervals, 10 date segments.

    5.  Functions of switch pulling and power off testing.

    6.  RS485 interface for PC communication; infrared communication, program setting and reading with palm computer set; infrared remote reading (manual recording).

    7.  LCD display for various parameters setting and   measurement data.

    8.  Realization of parameters polling display. The polling parameters (no more than 32 items) and time can be preset. The order of the polling parameters can also be preset arbitrarily.

    9. The measurement RMS of voltage, current and frequency.

   10. Functions for programmable prohibit, data clear and demand reset.

   11. Customer may select the inner power off reading mode which can, in the condition of power off and  no outer direct power supply, do meter reading with infrared remote controller for more than 1000 times readings. This reading mode does not influence the life of data saving battery.
