DJW-WB 20KVA / 30KVA Micro-controlled Non-contact Compensation 1Phase Series voltage regulator stabilizer

  • DJW-WB-50KVA / 60KVA
  • NQQK
1). Feature:
Integrating the advance duplex winding compensation mode、non-contact Switch and microcomputer controlled regulating
technology. It has the fea tures 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 add-
        ition adjustment, display、alarm and  protection of open-phase、overrun and malfunction etc.
Broadcast & Television system, Microwave telecommunication Unattended station, Industrial control system, 
Computer system, Industrial equipment supporting, Elevator supporting etc. Occasions that requires regulated power source.
