A Power Factor Controller (PFC) is an intelligent monitoring and switching device that continuously measures an electrical system’s power factor & automatically
engages or disengages capacitor bank stages to maintain optimal power-factor levels. In the case of Neptune’s PFC solutions, the controller pairs precise digital
sensing with multi-step capacitor switching to reduce reactive power, minimise utility penalties, lower energy losses and improve overall system stability. By ensuring
the power factor stays close tounity despite fluctuating loads, Neptune’s PFC helps commercial, industrial and institutional facilities enhance electrical efficiency and
extend equipment life.
