RS485 / Infrared 3 Phase Electric Meter , High Accuracy Multi Tariff Energy Meter

Three Phase Meter is an industrial meter which measures and records active energy, reactive energy,active maximum demand andreal time values of the power grid with TOU features. Data and parametersare displayed on LCD and can be read out through optical port or RS485 port. The user's power consumption can be checked by analyzing historical data and load profile. Event log of the meter helps determine the meter status as well as power grid conditions.

Features
1. Product's 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. Reliable Design—Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.

10. Cover for Meter—Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.
11. Communication Mode—Infrared+RS485 interface or double RS485 interface.
