Product Description

The three-phase intelligent current and voltmeter is designed for the power intelligent monitoring needs of power systems, industrial and mining enterprises, public facilities, smart buildings, etc. It can measure all common power parameters in the three-phase power grid with high precision, such as three-phase voltage, three-phase current, Frequency, with communication interface, analog output, relay output control and other functions.

The three-phase intelligent current and voltmeter has a variety of extended function input and output methods to choose from: 1 communication interface, 3 analog output, 4 relay output, local or remote switch signal monitoring and control output function ("remote signal ”And “remote control” function), 4-way switch monitoring function.

The three-phase intelligent current and voltmeter has an extremely high cost-performance ratio, and can directly replace conventional power transmitters, measuring indicating instruments, and related auxiliary units. As an advanced intelligent and digital power grid front-end collection component, it has been widely used Used in various control systems, SCADA systems and energy management systems, substation automation, distribution network automation, community power monitoring, industrial automation, intelligent buildings, intelligent distribution panels, switch cabinets, with easy installation, simple wiring, and convenient maintenance , The project is small, the input parameters can be set on-site programmable, and it can complete the networking of different PLC and industrial control computer communication software in the industry.
