Product Description
An efficient and intelligent DC energy meter
1.Product profile
This product is an intelligent DC energy meter developed based on the basic needs of the company's customers and combined with the technical accumulation of the company's existing products. It is mainly used for monitoring and energy consumption measurement of basic parameters such as current and voltage of various electrical equipment. It is used for measuring four DC output circuits based on one voltage. After installation, it can be directly connected to the backend software for monitoring through 4G communication, and has a local human-machine interface for operation.
