Three Phase Lora Smart Meter , Multi Tariff Energy Meter With Lora RF Module TOU / RTC
Main Features:
● Metering
- 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.Ø 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.
