KPBD/KPBS series three phase high power voltage regulator are energy saving new power supplies.It is composed of voltage regulator   circuit,control circuit,servo motor and so on.When the input voltage or load changes,   the controlcircuit for sampling,compared   with    the amplification,and then drive the servo motor rotates,   the pressure adjusting the position of the brush change,automatically adjust the coil number of turns ratio   and miantain the stability of the output voltage.So the regulators  have the  advantage of  for any load,large capacity,high efficiency,regulator range wide,high accuracy,strong  protection, no  waveform      distortion, ease of maintenance.Then this three phase high power voltage stabilizer  is widely used for industry ,agriculture,traffic,military,railway,metal working equipment,medical instruments etc.
