Power Factor Controller

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, minimize utility penalties, lower energy losses & improve overall system stability. By ensuring the power factor stays close to unity despite fluctuating loads, Neptune’s PFC helps commercial, industrial & institutional facilities enhance electrical efficiency & extend equipment life.
