Contactless voltage stabilizer
Widely applicable: covering power plants, industrial and mining enterprises, large heavy industrial equipment, industrial automation production lines, CNC machining centers, high-end precision instruments, processing equipment, high-power equipment test power supply, electronic communications, computers and peripheral equipment medical equipment, highway tunnels, construction sites and other places; from large factory voltage stabilized power supply to small personal household electrical equipment power supply, all power range products are complete. It is the first choice for solving voltage instability.
Wide voltage stabilization range: conventional +15%, [+20%, +30%, +40%, ±50%] voltage stabilization range optional.
Modular design: multiple parameter customization modes to meet different needs.
Support customization: various input and output voltages, input and output line systems, etc. can be customized.
Product features:
1.Intelligent instrument display: digital display system (display voltage, current, working status), clear, accurate, high resolution, mechanical button operation, safe and reliable, intelligent and convenient, simple and easy to understand.
2.Fast response speed: When the input voltage of the three-phase contactless voltage regulatorfluctuates, it can respond within 20ms. The output voltage can always be maintained at the rated output voltage value within the voltage regulation range, and will not affect any production equipment and instruments. There will be no overvoltage or undervoltage bypass phenomenon. 3. Power-on delay output: The contactless voltage regulator does not perform compensation function when it is turned on. It will perform corresponding compensation and voltage regulation after detecting the output voltage value 1 second after it is turned on. The output voltage will not be too high or too low when it is turned on, which will burn the electrical equipment. 4. Strong overload capacity: It can be used continuously under 100% rated load conditions, and can withstand 10 times the current for 10 milliseconds and 3 times the current for 1 minute without damaging the machine. 5. No distortion waveform: The current zero-crossing switching technology is adopted. There is no interruption during the switching process, and no surge current is generated, so that the waveform is not distorted. The isolation transformer used by the contactless voltage regulator is an isolation compensation transformer, that is, the main circuit and the compensation circuit are isolated. The advantage of this circuit is that when the thyristor of the compensation circuit switches the voltage gear at the current zero point, the voltage and current waveform of the main circuit will not produce spikes and interrupt the current. Instead, it is a standard sine wave.
3.Three-phase regulation: Each phase voltage is independently stabilized, without affecting each other, and the voltage stabilization accuracy is as high as +-1%. And each phase can set the output voltage separately according to the load requirements. If the output voltage value of each phase is set to the same, the three-phase output voltage imbalance is less than 1%.
4.High efficiency, energy saving, and environmental protection: The efficiency reaches more than 99%, the volume is small, it is convenient to transport, and it does not take up much space when placed.
5.Safe and reliable: It is equipped with overload, overvoltage, undervoltage, phase loss, short circuit, overheating protection, lightning protection and fault diagnosis functions, which can protect the load in 5 seconds
6.Strong preset function: output voltage value, protection limit, voltage stabilization accuracy, and voltage stabilization speed can be set arbitrarily
7.Bypass function, easy maintenance: It can switch between "voltage stabilization" and "bypass direct power supply", which is convenient for use when there is a fault repair.
8.Strong anti-interference ability: The power supply and sampling of the control circuit board all have high, medium and low frequency filtering circuits. The driving circuit of the control thyristor also uses optocoupler isolation output, which can resist pulse interference signals above 2000V. If there are spikes and interference signals in the grid voltage waveform, they can be dealt with calmly.
9.The voltage regulator is sampled by microcomputer numerical control DSP: If the input voltage waveform is true, the calculated voltage values are all effective values, which will not affect the output voltage change.
