Three phase remote cost control intelligent energy meter
The DTZY545 series is an intelligent energy meter launched by State Grid in 2009, which integrates functions such as metering, cost control, monitorin
Product details
Application scenarios
Residential users of large apartments and villas
General industrial and commercial users (implementing non residential electricity prices), such as shops
For users who require high accuracy in 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 energy meters directly without the need for additional wiring, except for the high-voltage power supply part
