Application scenarios
Residential users of large apartments and villas
General industrial and commercial users (implementing non residential electricity prices), such as shops
For customers with high precision requirements for non industrial energy metering, support active power level 0.5S, level 1 (default), and reactive power level 2
Users who hope to replace their existing electricity meters directly without the need for additional wiring, except for the high-voltage power supply
