Features
Flexible power factor improvement method
Multi-function, can filter harmonic current, can improve power factor by improving reactive power, can perform reactive power improvement while filtering, multiple modes are available
Real-time detection of dynamic compensation
Real-time detection of harmonic, automatic tracking of load harmonic changes through instantaneous current tracking control, highly controllable and fast responsive
Safe and reliable
Filtering performance is not affected by system impedance. Resonance prediction management effectively prevents capacitance capacity attenuation and avoids resonance risk
Complete product range
Our APF mainly include vertical module series, horizontal module series, wall mounting series, portable series, cabinet series, etc., which can meet the requirement of various environments and working conditions.
- horizontal module series: Small in size, suitable for a variety of cabinets, can be used for wall mounting;
- vertical module series: Independent air duct, vertical heat release, small cabinet, suitable for a variety of complex environments; with pulley, trolley structure, convenient for installation and maintenance
Convenient for maintenance
Standard modular design, plug and play, unlimited expansion, drawer fan
DSP intelligent monitoring
DSP high-speed detection and calculation, to ensure accurate and effective harmonic detection and compensation control, both intelligent monitoring and automatic fault diagnosis. Remote communication interface for real-time monitoring via PC
