General:
Integrating the advance duplex winding compensation mode¡¢non-contact switch and microcomputer controlled regulating technology, DJW-WB and SJW-WB single/three phase series microcomputer non-contact compensated voltage stabilizer 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.
1.Adopting the advanced duplex winding compensation technology, which ensure little waveform distortion.
2.Adopting one-chip computer to control the thrusters 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.
3.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.
