PFC2 30/50kVAR 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.

LED indicators: Green = DC Power ON, Red = Fault, Orange = Signal enabled, Red/Orange = Capacitors discharging
Cooling fan: +24Vdc (50KVAR model only)
Fan ’switch-on’: 50KVAR units typically +55ºC
Over Temperature: Trip in temperature: +90ºC ±1ºC (Status LED indicator ’flashes’ with ON/OFF rapid pulsing
Trip out temperature: +85ºC ±1ºC
Phase loss detection: Phase loss or Fuse failure orange and red LEDs flash alternately
Status LED Fault condition: Status LED indicator ’flashes’ ON/OFF continuously at 1.5 second intervals
Sensor loss detection: Status LED indicator ’flashes’ ON/OFF continuously in equal intervals
Power cable terminations: Supply and Load16mm² rising clamp terminal block
