Description

Features
1.Comprehensive compensation
It can achieve three functions: harmonic control, reactive power compensation, and regulation of three-phase unbalanced currents, providing comprehensive compensation for power quality issues.
The three functions can be combined and prioritized based on the load environment and specific needs.
2.Wide filtering range and fast response
The system can compensate for 2-50 harmonics simultaneously, or it can be set to compensate for a specific harmonic. The total current distortion rate after compensation is guaranteed to be less than 5%.
The harmonic current detection algorithm utilizes the efficient TTA algorithm, which is both fast and accurate, enabling a full response time of just 10ms.
3.High-end quality of core components
German original IGBT module, three-level topology.
The control system is comprised of the American TIDSP control chip, as well as ALTERA and CYCLONE 3 series FPGA chips, making it a powerful three-core system.
Additionally, TI’s double-ended high-speed input 12-bit A/D data conversion chip enhances the accuracy and reliability of signal sampling.
4.Efficient heat dissipation
The layered heat dissipation design creates an independent air duct, resulting in improved heat dissipation performance and effective isolation of dust and other pollutants.
5.Independent fan, detachable
The fan can be easily disassembled and assembled independently, making it convenient to replace and enhancing the reliability of heat dissipation.
6.Modular design
The combination of different capacity modules can be customized to enhance the overall reliability and maintainability of the entire machine.
7.Human-Machine Interface
Single modules can be equipped with a 5-inch LCD touchscreen, multiple modules can use an external 7-inch LCD touchscreen.
It is capable of monitoring a wide range of operating data for the product in real-time and also allows for online modification of control parameters.
Easy to use and can be paired with a mobile phone app for remote control.
