Features:
1. Product's Type: Remote, Remote Carrier, Local, Local Carrier.
2. Electric Power Measurement: Positive/reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 phase and active/reverse power in A, B, C phase which can be measured.
3. Muti Tariff: It can set for 2 time zones, 2 programs of daily time and swiching time (yy/mm/dd/hh/mm) of these two.
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 clear, program, timing, power downn, switch out, switch on, open meter cover and etc.
6. Communication Mode: Infrared + RS485 interface, carrier communication module, wireless GPRS/GSM, CDMA is optional.
7. Maximum Demand Measurement:
Measure total and time-sharing reverse active &reactive maximum demand and time of occurred.
Measure total and time-sharing reverse active &reactive maximum demand and time of occurred.
Measure total forward & reverse apparent maximum demand and time of occurred.
8. Real Time Measurement: Real time measurement of the phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency.
9. TOU: 4 Tariffs, 100 Holidays, 14 Season‐tables, 8time zone tables and each table on maximum 14 time zones.
10. Event Log: The last 10 records of following events: Powerdown, Programing, Cover opening, Terminal cover opening, Reverse power, The records include data and time.
10. Load profile: At least 4 load profile channels,Record at least 490days data when time interval is 30 minutes.
