PFC2 80/100kVAR Power Factor Switches

The PFC2 controllers are suitable for 3-wire, 3-phase floating-star or closed-delta configured capacitive loads for Power Factor Correction and can be used in capacitor banks with or without chokes fitted. They are designed to dramatically reduce the inrush current normally found with contactor-based systems and could be used in situations where rapid changes in Power Factor occur such as welding plants, lifts, cranes and wind-powered plants.
