Product description

GRIDCON® ACF Industrial version is the number one choice for challenging compensation tasks where reliability and safety are needed, for example, even beyond normal operating voltages and under challenging ambient conditions:

  • Operation up to 690 V and higher at full power without derating
  • Rated current can be extended in a modular manner from 125 A to 3,000 A, e.g. for STATCOM systems
  • High power density and compact design
  • Low losses
  • Very durable film capacitors
  • Overvoltage category III up to 1000 V – even in grids with isolated neutral point (IT network configuration)
  • Degree of protection up to IP 54 possible, optional external water cooling for complete encapsulation
  • Dynamic compensation of reactive power, harmonics, and flicker, as well as load balancing in one unit
     


Its very special plus points make GRIDCON® ACF Industrial version the number one choice in many Areas:

  • Production lines, e.g. automotive
  • Mining
  • Chemical industry
  • Larger printing plants
  • Cranes and transport systems
  • Offshore platforms and ships
  • Oil and gas
  • Paper industry
  • Steel processing
  • Water treatment and pump stations
