The basic principle of It adopts the latest DSP operation metering chip control technology, fast AC sampling technology, effective value correction technology current zero switching technology and fast compensation voltage regulator technology, the intelligent instrument, fast voltage regulator and fault diagnosis together, so that the product is safe, efficient and precise.
The drive circuit for controlling the thyristor can resist the pulse interference signal of more than 2000 V. If the voltage waveform of the power grid has a peak value, interference signal ， also Can deal with it calmly.
Zero crossing switching technology，more complete protection functions
Contactless zero-crossing switch switching, isolation transformer superposition voltage regulation, isolation transformer compensation, to achieve output waveform without distortion.
No machinery, no worries about maintenance
Adopt advanced integrated circuit, microcomputer central processing CPU, transmission faster, more stable and reliable, no mechanical, maintenance-free
Advantages
1. Intelligent instrument display: digital display system (display voltage, current), clear, accurate, high resolution, film
button operation, safe and reliable.
2. High speed response: when the input voltage fluctuation is large and frequent, due to the voltage regulator speed of 20
milliseconds, as long as the voltage regulator range is wide enough, the output voltage can always be maintained in the user set
voltage value, on any production equipment and instruments, does not produce voltage change.
3. Strong overload capacity: it can be used continuously under 100% rated load condition, and can withstand 10 milliseconds 10
times current, 1 minute 3 times current without damaging the machine.
4. No distortion: the zero-crossing current switching technology is adopted to ensure no interruption of current and surge current
in the switching process, so that the waveform has no distortion.
5. Three-phase separate regulation: each phase voltage is regulated independently without any influence on each other. The high
precision of voltage regulation is +-1%. And each phase can be set separately according to the load needs output voltage
6. High efficiency, energy saving, environmental protection, efficiency of more than 99%, small volume, convenient transportation,
placing less space
7. Safe and reliable: with overload, overvoltage, undervoltage, lack of phase, short circuit, overheat protection, lightning
protection and fault diagnosis functions, can 5 seconds to protect the load.
8. Bypass function, easy maintenance: it can switch between "voltage regulator" and "bypass direct power supply", which is
convenient to use in case of failure maintenance.
