Tayfun from TurkeyVeikong solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!
Cristian from ChileIt’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.
Brahim assad from SyriaVEIKONG VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.
160kw Vfd Line Reactor,
132KW Vfd Line Reactor
AC choke 400V AC 50HZ 300A output reactor used for 132KW motor
Description of Load Reactor:
VKS-OCL series Load Reactors are placed in series with electrical equipment to introduce a specific controlled impedance to the AC circuit. This series are applied at AC drive output side to suppress inrush voltage, reducing inrush and peak current, improving real power factor, restraining grid harmonics and improving the output current waveform. Line Reactor also known as Output Reactor.
Material Features of Load Reactor:
Flexible Meterial Choice:Selection of silicon steel,ferrite magnetic material of amorphous core according to the frequency of application;
Excellent Property:Due to foll winding structure,small DC resistance, strong resistance to electromagnetic force, good overload ability in short time
Reliable Performance:F-class insulation materials are used, which ensure products maintain reliable performance in harsh working condition.
Low Noise: Designed with low magnetic flux density,the reactors of high linearit.With powerful overload sheets, the reactor noise is low

Application of Load Reactor:
It is recommended to use input reactors in the following circumstances:
1. frequency converters in parallel close connection.
2. line power supply has obvious disturbance from other devices (interference, over voltage).
3. there is voltage imbalance between the phases of the line power supply, exceeding 1.8% of the rated voltage.
4. a large number of converters are installed on the same line.
5. reduce cos C overload on the correction capacitor if there is a power factor correction device in the device.
6. power supply capacity is 60KVA and above, and frequency converter installation location is within 10M of large capacity power supply.
7. the frequency converter is powered by a very low impedance line (10 times higher than the inverter's rated value).

VEIKONG Input and output reactor for variable frequency speed regulation: inverter and governor during use, often suffer from the surge current and surge voltage impact, the performance will be severely damaged and the service life of the converter and the governor, so to use input reactor arranged on the front, to suppress the surge voltage and surge current protection, inverter and governor, extend the service life and prevent the harmonic interference, at the same time, as the frequency converter and adopts frequency conversion speed governor is the way, so often produce hormonics and waveform distortion in the speed, will affect the normal use of equipment, therefore, require the installation of a reactor output on the output side, to filter out the harmonic voltage and current, improve the quality of power grid. Our produced Input and output reactor, using high quality imported silicon steel sheet, the advanced technology refined, have the advantages of small volume, low temprature rise, no noise etc..
Our AC input and output reactor can match with SIEMENS, ABB, Hitachi, Toshiba, Matsushita, Sanken, Yaskawa, PU, Danfoss, Fuji, LG, OMRON, Continental, OMRON, moden Schneider, Lenze, Emerson, and other domestic and foreign brands converters.
