Power factor controller RVT
Smart power factor controller for automatic capacitor banks
The power factor controller is one of the most important components of the power factor correction equipment. As such, it plays a key role in the control and monitoring of the power factor and the system power quality.
The RVT touch screen offers power factor control, measurements, monitoring and communication in a user-friendly fashion.
Applications
The RVT controllers can be used to control power factor in industrial and commercial networks. Application examples include power factor control in buildings, mining steel industry, chemical, pulp and paper, cement, plastics, printing and food industries.
