Product details
Product Overview:
The intelligent three-phase ammeter adopts AC sampling technology, which can measure the three-phase current in the power grid. Users can set the multiplier through the instrument panel buttons, and the cost-effectiveness is extremely high. It has the characteristics of easy installation, simple wiring, convenient maintenance, small engineering quantity, programmable input parameters on site, and can complete network communication with different PLCs and industrial control computers in the industry. Realize intelligent management of enterprises and institutions, and provide a basis for the special audit of electrical energy conservation.
