Three Phase Three Wire Lora Smart Meter Active Energy Measuring with Switch On& Off

Features:

1. Remote ON/OFF Control

2. Metering

For active combination, reactive combination 1 and reactive combination 2 power, the valid range is –799999.99~799999.99, and unit is kWh or kvarh.

Positive/reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 quadrants and active/reactive power in A, B, C phase which can be measured. It can set tagged words of active/reactive combination, aim at positive/reverse active power and reactive power in 4 quadrants, to restructure active combination, reactive combination 1 and reactive combination 2.

All power can be time-share measured by total and max 4 tariffs. (No time-share measurement for power in A, B, C phases)
It can storage power data for 12 settlement period.
For positive/reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 quadrants and active/reactive power in A, B, C phases, the valid range is 0~999999.99, and unit is kWh or kvarh

3. Demand Measurement

4. Settlement Function

5. Tariff

Public holiday can be set, including date and daily period meter number of each public holiday.
Weekend holiday can be set, which controlled by tagged word, daily period meter number can also be set for each weekend holiday.
If the same for public holiday and weekend holiday, daily period meter number of public holiday will be used.
Automatic changeover of century calendar, time, leap year.
If tariff number in the period of daily period is larger than tariffs, or the tariffs is 0, the power in the period reckon in tariff 1.

It can set solution for 2 time zones, 2 daily periods and switching time (yy/mm/dd/hh/mm) of both two.1st time zone and daily period solution is default selection, when reach switching time of time zone, it changes to 2nd solution of time zone, and when reach switching time of daily period, it changes to 2nd solution of daily period. Then set switching time again for 2 solutions,when reach switching time of time zone, it changes to 1st solution of time zone, and when reach switching time of daily period, it changes to 1st solution of daily period. Switching time would be clear since changes of time zone solution and daily period solution.
Max 4 tariffs. Each time zone solution can set 14 time zones as max, with starting time and meter number of daily period which is used. Each daily period solution can set 8 daily periods as max, 14 periods per day, with starting time and tariff which is used. Minimum interval of periods is 15 mins., and period interval is larger than actual demand cycle valve, can be set over 00:00
