2. Features:

  • Non-contact, CPU intelligent SCR control, Digital Circuit Control, stable and reliable
  • High efficiency>99%
  • High precision ±1%,2%, ±3%, ±5% (adjustable)
  • Non-contactanti-interruptmaintenance freeno mechanical failure and carbon brush attrition.
  • Intelligent instrument display: intelligent instrument real-time display of voltage, current, power, such as RMS, clear, accurate, high resolution, thin-film button operation, safe and reliable.
  • Three-phase separately adjustmentOutput voltage unbalance is less than 1% so that guarantee the precision of each phase is stable.
  • Wide application range: Widen voltage stable range, it can meet the need to work in the poor voltage condition
  • Quickly response: stabilization response within 40mm, no influence on computerized automation, Machine and Equipment.
  • Full protection function: fault display and alert in over loaded, over voltage, lack of voltage, lack of phase, short circuit, over heat, confirming appliance running in a safety condition.
  • Preset function: Protective limit can set freely.
  • Strong ability for instantaneous overload: The high quality material can confirm excellent performance. This machine can continuously run in 100% rated load. Further more, it can bear the instantaneous overload without any harmfulness.
  • Well-adapted ability: This stabilizer have high adaptability toward bad and complicated live wire entanglement, so it can work continuously and stably .  
  • No distortion: We use current zero-crossing switching technology. There is no current interruption, no surging current and waveform distortion during the switching processes.
  • Low loss: least power loss; No-load loss is less than 0.5% , saving money on electricity for customer.
  • Bypass function, convenience in maintain: It can switch between voltage stabilizer and bypass power supply ,which make it convenient to be maintained.
