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
Active power filter 480a apf panel for dynamic harmonics compensation
Active power filter(APF/AHF for short) is a perfect comprehensive solution to power quality problems with power grid such as harmonic wave(can filter 2nd to 50th harmonic interference completely), reactive power, and 3 phase load unbalance.APF is connected in parallel in power grid, to detect the harmonic wave in power grid in real time, generate the reverse-phase compensation current through the converter, and dynamically filter the harmonic wave in power grid. The operation of APF is unaffected by power grid structure and load type, and it will not produce harmonic oscillation with the system, thus perfectly realizing harmonic wave control of various loads. APF can also realize dynamic reactive compensation, and control the capacitor switching, to improve the power factor of power grid. Meanwhile, APF has the function of controlling the 3 phase load current unbalance, thus comprehensively solving various power quality problems with power grid.
Applying world advanced power component
The world advanced IGBT component is applied, and the main circuit is a bridge full-control type PWM converter, which is featured by high power density and high reliability.
Digital control system
DSP high-speed detection and computation is employed, to ensure precise and effective current detection and compensation control; full digital control system is applied, so that the entire control process is realized by the software, to make the entire control system simpler and more reliable.
Monitoring and display system
Intelligent monitoring and display system is applied for flexible operation of the devices, with the operation parameters and working condition displayed clearly, the function of fault self-diagnosis and telecommunication interface for real-time communication with the host computer.
Unique group control system
SIKES is the first APF manufacturer in China that combines both active technology and passive technology to realize an intelligent control system using the active module to control the switching of the passive module, namely an integrated control system, to ensure the reliable operation of the equipment to the most extent.
