O PFW03 é um equipamento de automação destinado ao monitoramento permanente da potência reativa da instalação e ao controle do fator de potência.
Description
The PFW is an automation device for permanently monitoring the reactive power of the installation and controlling the power factor. This control in the PFW is done by connecting and disconnecting steps of capacitors. Therefore, the Automatic Power Factor Controller enables the power distribution system to operate at maximum efficiency by reducing the reactive power. In addition, it informs electrical parameters such as: current, voltage, power, energy, demands and maximum and minimum values.
Main c haracteristics
