Product Description Three phase rail type electric meter1.Product profileThe three-phase rail type comprehensive measurement and control instrument is mainly used in the field of electricity information collection for three-phase power networks with frequencies ranging from 45 to 65Hz. It can measure all electrical parameters in the power grid and exchange data with the upper computer through communication. Users can set the internal parameters of the product according to the actual situation on site, which is convenient to use, easy to operate, and has high accuracy; It is widely used in various power Internet scenarios.It can achieve high-precision measurement and metrology to meet measurement and other applications. Adopting standard DIN35mm rail installation and modular structural design, it can be easily installed inside the distribution box. Users can easily switch displays and set parameters on-site, making it flexible and convenient to use. It can directly replace conventional power transmitters and other auxiliary units as an advanced intelligent digital power grid front-end acquisition component, widely used in various control systems, substation automation systems, and distribution automation systems. It has the characteristics of easy installation, simple wiring, convenient maintenance, and small engineering quantity, and can flexibly network with various communication software.2.Product
