Intelligent non - contact compensated AC voltage regulator


Working principle


This intelligent non-contact compensated AC voltage

regulator is adopted the latest high-speed DSP

chip control technology, fast AC sampling technology,

RMS correction technology, voltage and current

zero-crossing switching technology and fast

compensation regulator technology, combining the

smart instrument, fast regulator and fault

diagnosis togetherA.It leads the product

to be with high level safe, efficient and sophisticated.

The regulator is mainly composed of isolation transformer, SCR module, DSP control core, fast voltage regulator technology and safety protection device.

With the real-time monitoring output voltage by the DSP, fast calculation chip and control SCR module, to adjust the voltage range and polarity of the of the compensation transformer, the AVR can achieve fast regulation effectively.


Main Features:


High efficiency: more than 98%,low loss

  • High efficiency: more than 98%, low self-loss
  • High output accuracy ± 1%
  • Intelligent instrument display: real-time display accurate voltage, current RMS value, high resolution, thin film key operation, safe and reliable
  • Three-phase adjustment: three-phase independently regulation, to ensure that the output voltage of each phase is accurate.
  • Wide range of applications: Wide voltage range, to satisfy poor power grid quality or with large voltage fluctuation power conditions
  • High-speed response: Within 10ms,without any effect on computer, automation, equipment ect.
  • Comprehensive Protection: phase loss, wrong phase, over temperature, overload, overvoltage, under voltage, short circuit, fuse protection ect. to ensure safe operation of the regulator & load.
  • Preset function: output voltage, overload, overvoltage,response speed and other parameters can be arbitrarily set within capacity rating.
  • Strong Overload capacity: the machine uses high-quality devices, excellent performance, can be continuously working with 100% rated load, and can withstand transient overload without damage to the machine.
  • Strong adaptability: strong adaptability to the grid and load, can reliably, continuously and stably work in a variety of harsh power grid or with complex load conditions
  • No distortion: use voltage and current zero-crossing switching technology, no cutoff, no inrush current, the output waveform without distortion in the switching process
  • Low loss: less than 0.5% loss without load , which saves a lot of electricity fee for end users.
  • Low loss: less than 0.5% loss without load under rated voltage, which saves a lot of electricity for customers
