Feautre
Integrating the advance duplex winding compensation mode、non-contact Switch and microcomputer controlled regulating technology. It has the features of high efficiency and energy-saving、fast adjustment、three phase automatic balanced no mechanical malfunction or carbon brush wearing, also with the functions of delay、under/over voltage alarm and protection.
   • Adopting the advanced duplex winding compensation technology which ensure little waveform distortion.
   • Adopting one-chip computer to control the thyristor and shifting combination for timing compensation adjustment enable it to realize the fast non-contact  adjustment. Strong instantaneous overload capacity makes it available with various loads
  • Adopting one-chip computer split-phase control, it has the functions of delay starting-up, three-phase automatic balance adjustment, display、alarm andprotection of open-phase,overrun and malfunction etc.
