Active Power Filter (APF) is a new type electronic device which is used to prevent dynamic harmonic and compensate reactive power. It can compensate the size-changing and frequency-changing harmonic wave and changing reactive power.
More Functions and More Models
This devices is multi-functional. It can be used to compensate the reactive power, harmonic, reactive power and harmonic, and three-phase imbalance.
The harmonic can be compensated by times; and the ratios of reactive power compensation can be set.
With：7 inches color HD touch screen. The screen can display the parameters of system and device.
IoT is adapted, which can enable monitoring and operating in time.
Advanced Control Strategy and Topological Structure Design
This device based on IRPT detecting technologies, the harmonic current can be monitored in time and the change of loading harmonic can be traced, which make this device highly controllable and reactive.
The unique phase-splitting harmonic extraction algorithm is adapted. When the three-phase load is imbalanced, each phase can be controlled independently. Besides, when the capacity is enough, the function to remove the imbalance can be chosen.
The LCL topological structure of filter is adapted, when outputting harmonic current and the high frequency IGBT switching harmonic interference cannot be introduced. It can be adapted in any field with grid system impedance and no resonance will happen.
Complete Protection, High Stability
SOJO Patented technology, peak effective values and double current limit algorithm, the device output can be limited to 100% automatically, without overload risk.
Complete protection, in order to ensure the system work reliably and safely.
Fault Self-check Function
Fault Alarm and Recall
High integration, modularization and serialization
Modularization, small and light, high power density, easy to maintain and install
Combination parallel machine can satisfy different demands. When realizing standardization, the reliability and maintainability are improved, which makes maintenance and installation easier.
Single module independent air duct design, which can isolate dust and improve thermal performance.
