The advantages of this technology as compared to manual phase selection are.

  • Phase selection is instantaneous and avoids delay of phase selection due to this machines lightings AC units do not suffer black outs.
  • No moving parts as in the case of rotator switches.
  • Avoids sparking, spikes and surges
  • Moisture proof.
  • As there are no mechanical contacts the solid state selector can work in extreme climatic conditions and temperatures.
