SJW-WB Micro-controlled Compensation Voltage Stabilizer with Non-contact

Product Description:

Feature

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.
