DZW series Intelligent contactless voltage stabilizer

It'is a patented regulator with internationally leading level as developed and manufactured by our company.It uses integrated circuit to control a few of zero-crossing voltage switches of thyristors in special subsequence ,changing the size and polarity of offset voltage.This is the perfect combination of thyristor's switching technology and transformers technology.

Installation conditions:

 1.Alitude≤2500m.

  2.Ambient temperature:max temperature≤40℃,minimum≥-25℃

  3.Relative humidity:the max RH in the wettest month is 90%.

  4.To be installed in the place without violent vibration or collision.

 

Strengths:

 1.Smart CPU control,large LCD display,human-machine operation interface.

  2.The process of fast regulation is completed within 40ms,accessible with various power generators.

  3.3-phase regulation,contactless,without wear and spark,free maintenance.

  4.Strong overload capacity,without damage bearing 10times current for 1 second or 3 times current for 1 minute.

  5.Energy conservation,efficiency up to 90%,power consumption ≤1%,save power and money.

  6.Anti-interference,strong purifying capacity,without distortion of waveform,with pure output voltage.

  7.With the protective functions for overvoltage,undervoltage,short-circuit,missing phase,automatic bypass.

  8.Preset function of strong output voltage,arbitral setting of protective limit.

  9.Can be switched between regulation and bypass power supply.

 

Application:

CNS machining center,slow wire cutting,mirror-surface electrical discharge machine,SMT machine,numerical control punch,PCB drilling machine,automatic equipment,CNC,imported printing machine,medical equipment,injection machine,laser machine,automatic plug-in machine,nuclear magnetic resonance machine and etc.
