GTZW-S/D 10-3000kVA
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.

- 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

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
Perfect Application:
Industry, transportation, post and telecommunications, defense,
railway, scientific research and other fields of large-scale
mechanical and electrical equipment, metal processing
equipment,.Like production lines, elevators, medical equipment,
embroidery textile equipment, air conditioning, radio and
television, household appliances and building lighting and other
electrical equipment ,which needs stable voltage.
