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.

Product Description
AC choke output reactor used for 5.5kw 7.5kw 11kw 15kw AC drive
Purpose
The filter reactor is used in the low-voltage filter cabinet, connected in series with the filter capacitor, tuned to a certain resonance frequency, and used to absorb the harmonic current of the corresponding frequency in the power grid. There are a large number of harmonic sources such as rectifiers, converters, and frequency converters in the low-voltage power grid, and the high-order harmonics generated by them will seriously endanger the safe operation of the main transformer and other electrical equipment in the system. After the filter reactor is connected in series with the capacitor, it can not only effectively absorb the harmonics of the power grid, but also improve the power factor of the system and play a greater role in the safe operation of the system.
Material Features of Load Reactor:
1. Reducing working frequency inverter and DC speed regulator interference to other devices, like harmonic interference, waveform distortion.
2. Enhance the capability of frequency inverter resistance to voltage unbalance degree. (Unbalance degree > 1.8% of rated voltage). 3. 3. Protection frequency inverter rectifier modules and related components damage from pinnacle capacitive current due to low internal power resistance. (When power supply capacity is 5 times larger than frequency inverter capacity).
4. Improve the power factor of power supply, lower harmonic current content in the inverter power supply.
5. Reduce current and voltage waveform distortion rate, improve the quality of power supply.

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).
