Micro-Controlled Non-Contact Compensation Voltage Regulator/Stabilizer (WJW-WB/SJW-WB)

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
       And protection of open-phase,overrun and malfunction etc.
