Digital multi-function power meter It is designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It can measure all common power parameters, such as three-phase current, voltage, active and reactive power, electricity, harmonics, etc. Because the power meter also has a complete communication networking function, we call it a network power meter. It is ideal for real-time power monitoring systems.
The meter has a high performance-to-price ratio and can directly replace conventional power transmitters and measuring instruments. As an advanced intelligent and digital front-end acquisition element, this series of network instruments has been widely used in various control systems, SCADA systems and energy management systems.
