Three phase electronic multifunctional front board installed energy meter is a kind of new style three phase four wire multifunctional energy meter. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21 and class 2 three phase reactive energy meter in international standard IEC 62053-23. It can accurately and directly measure 50 Hz or 60 Hz active energy consumption from three-phase four-wire AC electricity net.
This meter has LCD monitors which shows the active energy power consumption, and there are far infrared and RS485 communication module in it ,with features of good reliability,, specious appearance etc and its feature of multi-functional make it convenient to contact with all kinds of AMR system.
1. Products Type-Three Phase Three Wires, Three Phase Four Wires.
2. Electric Power Measurement-Positive/ reverse active power, positive/reverse apparent power>, reactive power in 1,2,3,4 phase and active/reactive power in A, B, C phase which can be measured. It can set tagged words of active and reactive group to restructure the positive/reverse active power and reactive power in 4 phases, and then for active group, reactive group1 and reactive group 2. It can storage power data for 12 settlement period.
3. Multi Tariff-It can set for 2 time zones, 2 programs of daily time and switching time (yy/mm/dd/hh/mm) of these two. Set for public holidays, date of each and meter number of daily time; Set for weekly holiday which controlled by its tagged words, and also set for meter number of daily time for each weekly holiday.
4. Demand Measuring-It can measure max demand and the time when it occurred for positive/ reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 phase, reactive group 1 and 2.
5. Event Log-With function for logging events such as no voltage, under voltage, over voltage, loss of phase, full loss of pressure, no current, over current and etc.
6. Electricity Freezing-With multi freezing ways of instantaneous freezing, timing freezing, day freezing, appoint freezing, on hour freezing and etc.
7. Load Profile-Support for 6 load data, and the time interval can be set for any time which from 1 to 60 mins. The time interval for each load can be the same or not.
8. Measure Function-It can measure voltage, current, phase angle, apparent power, active power, reactive power, power factor and grid frequency of total and each A, B, C phase, also it can show the direction of power.
9. Communication Mode-Infrared+RS485 interface or double RS485 interface.
