The three-phase intelligent energy meter is a high-precision intelligent instrument developed to meet the needs of the State Grid Corporation of China's smart grid construction. This type of electricity meter focuses on expanding functions such as information storage and processing, real-time monitoring, automatic control, and information exchange on the basis of electricity metering. It is a multifunctional electricity meter, and these functions are added around a strong smart grid to meet the needs of electricity metering, marketing management, and customer service. There are four main types of products:
DTZY2026 ： 1.0 level three-phase remote cost control intelligent energy meter (RS485)
DTZY2026-Z： 1.0 level three-phase remote cost control intelligent energy meter (carrier)
DTZY2026C： 1.0 level three-phase CPU card cost control intelligent energy meter
DTZY2026C-Z: 1.0 level three-phase CPU card cost control intelligent energy meter (carrier).
