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.
3. Demand Measurement
4. Settlement Function
5. Tariff
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.
