main features

shouldElectric energy meterDesigned with advanced microcontroller processing system, it has the advantages of simple circuit, high reliability, and high accuracy. This product has advanced software, hardware, and structural design technology, high measurement accuracy, and combines microcontroller resources to achieve bidirectional communication of active energy measurement for solar and photovoltaic power generation users. It measures more than 20 electrical parameters such as three-phase real-time current, voltage, active power, reactive power, and power factor, and has RS-485 communication function. It has good anti-interference and anti attack performance, wide working temperature range, and can work stably and reliably for a long time. The various error performance indicators of this product comply with the technical requirements of standards such as GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and DL/T 645-2007 "Communication Protocol for Multi functional Energy Meters" (MODBUS communication protocol can be customized).

This energy meter adopts modular design, which has the advantages of small size, easy installation, and easy networking, making it easy to achieve terminal distribution energy measurement. This product can be directly installed together with air switches, circuit breakers, and contactors, making it a signal acquisition unit with power phase separation management requirements for factories, schools, hospitals, shopping malls, and other places.
